 ## Impact
 
-### Pilot
+### Kubernetes Ingress API Version `networking.k8s.io/v1beta1`
 
-Metrics will continue to function normally up to 2.8, when they will be disabled.  
-In 2.9, the Pilot platform and all Traefik integration code will be permanently removed.
+The Kubernetes Ingress API Version `networking.k8s.io/v1beta1` support is removed in v3. 
+Please use the API Group `networking.k8s.io/v1` instead.
 
-Starting on 2.7 the pilot token will not be a requirement anymore for plugins.  
-Since 2.8, a [new plugin catalog](https://plugins.traefik.io) is available, decoupled from Pilot.
+### Traefik CRD Definitions API Version `apiextensions.k8s.io/v1beta1`
 
-### Consul Enterprise Namespace
-
-Starting on 2.8 the `namespace` option of Consul and Consul Catalog providers is deprecated, 
-please use the `namespaces` options instead.  
-
-### TLS 1.0 and 1.1
-
-Starting on 2.8 the default TLS options will use the minimum version of TLS 1.2. Of course, it can still be overridden with custom configuration.  
-
-### Nomad Namespace
-
-Starting on 2.10 the `namespace` option of the Nomad provider is deprecated,
-please use the `namespaces` options instead.
-
-### Kubernetes CRD Provider API Group `traefik.containo.us`
-
-In v2.10, the Kubernetes CRD provider API Group `traefik.containo.us` is deprecated, and its support will end starting with Traefik v3. Please use the API Group `traefik.io` instead.
-
-### Kubernetes CRD Provider API Version `traefik.io/v1alpha1`
-
-The Kubernetes CRD provider API Version `traefik.io/v1alpha1` will subsequently be deprecated in Traefik v3. The next version will be `traefik.io/v1`.
+The Traefik CRD definitions API Version `apiextensions.k8s.io/v1beta1` support is removed in v3.
+Please use the API Group `apiextensions.k8s.io/v1` instead.

+
+Secure the backend connection with SPIFFE.
+{: .subtitle }
+
+[SPIFFE](https://spiffe.io/docs/latest/spiffe-about/overview/) (Secure Production Identity Framework For Everyone), 
+provides a secure identity in the form of a specially crafted X.509 certificate, 
+to every workload in an environment.
+
+Traefik is able to connect to the Workload API to obtain an x509-SVID used to secure the connection with SPIFFE enabled backends.
+
+## Configuration
+
+### General
+
+Enabling SPIFFE is part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
+It can be defined by using a file (YAML or TOML) or CLI arguments.
+
+### Workload API
+
+The `workloadAPIAddr` configuration defines the address of the SPIFFE [Workload API](https://spiffe.io/docs/latest/spiffe-about/spiffe-concepts/#spiffe-workload-api).
+
+!!! info "Enabling SPIFFE in ServersTransports"
+
+    Enabling SPIFFE does not imply that backend connections are going to use it automatically.
+    Each [ServersTransport](../routing/services/index.md#serverstransport_1) or [TCPServersTransport](../routing/services/index.md#serverstransport_2),
+	that is meant to be secured with SPIFFE,
+	must explicitly enable it (see [SPIFFE with ServersTransport](../routing/services/index.md#spiffe) or [SPIFFE with TCPServersTransport](../routing/services/index.md#spiffe_1)).
+
+!!! warning "SPIFFE can cause Traefik to stall"
+	When using SPIFFE,
+	Traefik will wait for the first SVID to be delivered before starting.
+	If Traefik is hanging when waiting on SPIFFE SVID delivery,
+	please double check that it is correctly registered as workload in your SPIFFE infrastructure.

+# Tailscale
+
+Provision TLS certificates for your internal Tailscale services.
+{: .subtitle }
+
+To protect a service with TLS, a certificate from a public Certificate Authority is needed.
+In addition to its vpn role, Tailscale can also [provide certificates](https://tailscale.com/kb/1153/enabling-https/) for the machines in your Tailscale network.
+
+## Certificate resolvers
+
+To obtain a TLS certificate from the Tailscale daemon,
+a Tailscale certificate resolver needs to be configured as below.
+
+!!! info "Referencing a certificate resolver"
+
+    Defining a certificate resolver does not imply that routers are going to use it automatically.
+    Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.

+
+## Domain Definition
+
+A certificate resolver requests certificates for a set of domain names inferred from routers, according to the following:
+
+- If the router has a [`tls.domains`](../routing/routers/index.md#domains) option set,
+  then the certificate resolver derives this router domain name from the `main` option of `tls.domains`.
+
+- Otherwise, the certificate resolver derives the domain name from any `Host()` or `HostSNI()` matchers
+  in the [router's rule](../routing/routers/index.md#rule).
+
+!!! info "Tailscale Domain Format"
+
+    The domain is only taken into account if it is a Tailscale-specific one,
+    i.e. of the form `machine-name.domains-alias.ts.net`.

-# Welcome
+# What is Traefik?
 
 ![Architecture](assets/img/traefik-architecture.png)
 
 Traefik is an [open-source](https://github.com/traefik/traefik) *Application Proxy* that makes publishing your services a fun and easy experience. 
-It receives requests on behalf of your system and identifies which components are responsible for handling them, and routes them securely. 
+It receives requests on behalf of your system, identifies which components are responsible for handling them, and routes them securely. 
 
 What sets Traefik apart, besides its many features, is that it automatically discovers the right configuration for your services. 
 The magic happens when Traefik inspects your infrastructure, where it finds relevant information and discovers which service serves which request. 
 
-Traefik is natively compliant with every major cluster technology, such as Kubernetes, Docker Swarm, AWS, Mesos, Marathon, and [the list goes on](providers/overview.md); and can handle many at the same time. (It even works for legacy software running on bare metal.)
+Traefik is natively compliant with every major cluster technology, such as Kubernetes, Docker Swarm, AWS, and [the list goes on](./reference/install-configuration/providers/overview.md); and can handle many at the same time. (It even works for legacy software running on bare metal.)
  
 With Traefik, there is no need to maintain and synchronize a separate configuration file: everything happens automatically, in real time (no restarts, no connection interruptions).
 With Traefik, you spend time developing and deploying new features to your system, not on configuring and maintaining its working state.
 
 And if your needs change, you can add API gateway and API management capabilities seamlessly to your existing Traefik deployments. It takes less than a minute, there’s no rip-and-replace, and all your configurations are preserved. See this in action in [our API gateway demo video](https://info.traefik.io/watch-traefik-api-gw-demo?cta=docs).
 
-Developing Traefik, our main goal is to make it effortless to use, and we're sure you'll enjoy it.
+!!! quote "From the Traefik Maintainer Team" 
+    When developing Traefik, our main goal is to make it easy to use, and we're sure you'll enjoy it.
 
--- The Traefik Maintainer Team 
+## Personas
+
+Traefik supports different needs depending on your background. We keep three user personas in mind as we build and organize these docs:
+
+- **Beginners**: You are new to Traefik or new to reverse proxies. You want simple, guided steps to set things up without diving too deep into advanced topics.
+- **DevOps Engineers**: You manage infrastructure or clusters (Docker, Kubernetes, or other orchestrators). You integrate Traefik into your environment and value reliability, performance, and streamlined deployments.
+- **Developers**: You create and deploy applications or APIs. You focus on how to expose your services through Traefik, apply routing rules, and integrate it with your development workflow.
+
+## Core Concepts
+
+Traefik’s main concepts help you understand how requests flow to your services:
+
+- [Entrypoints](./reference/install-configuration/entrypoints.md) are the network entry points into Traefik. They define the port that will receive the packets and whether to listen for TCP or UDP.
+- [Routers](./reference/routing-configuration/http/router/rules-and-priority.md) are in charge of connecting incoming requests to the services that can handle them. In the process, routers may use pieces of [middleware](./reference/routing-configuration/http/middlewares/overview.md) to update the request or act before forwarding the request to the service.
+- [Services](./reference/routing-configuration/http/load-balancing/service.md) are responsible for configuring how to reach the actual services that will eventually handle the incoming requests.
+- [Providers](./reference/install-configuration/providers/overview.md) are infrastructure components, whether orchestrators, container engines, cloud providers, or key-value stores. The idea is that Traefik queries the provider APIs in order to find relevant information about routing, and when Traefik detects a change, it dynamically updates the routes.
+
+These concepts work together to manage your traffic from the moment a request arrives until it reaches your application.
+
+## How to Use the Documentation
+
+- **Navigation**: Each main section focuses on a specific stage of working with Traefik - installing, exposing services, observing, extending & migrating. 
+Use the sidebar to navigate to the section that is most appropriate for your needs.
+- **Practical Examples**: You will see code snippets and configuration examples for different environments (YAML/TOML, Labels, & Tags).
+- **Reference**: When you need to look up technical details, our reference section provides a deep dive into configuration options and key terms.

 Handling Content-Type auto-detection

-The Content-Type middleware - or rather its `autoDetect` option -
-specifies whether to let the `Content-Type` header,
-if it has not been defined by the backend,
-be automatically set to a value derived from the contents of the response.
-
-As a proxy, the default behavior should be to leave the header alone,
-regardless of what the backend did with it.
-However, the historic default was to always auto-detect and set the header if it was not already defined,
-and altering this behavior would be a breaking change which would impact many users.
-
-This middleware exists to enable the correct behavior until at least the default one can be changed in a future version.
+The Content-Type middleware sets the `Content-Type` header value to the media type detected from the response content,
+when it is not set by the backend.
 
 !!! info
 
-    As explained above, for compatibility reasons the default behavior on a router (without this middleware),
-    is still to automatically set the `Content-Type` header.
-    Therefore, given the default value of the `autoDetect` option (false),
-    simply enabling this middleware for a router switches the router's behavior.
-
     The scope of the Content-Type middleware is the MIME type detection done by the core of Traefik (the server part).
     Therefore, it has no effect against any other `Content-Type` header modifications (e.g.: in another middleware such as compress).

+Converting gRPC Web requests to HTTP/2 gRPC requests.
+{: .subtitle }
+
+The GrpcWeb middleware converts gRPC Web requests to HTTP/2 gRPC requests before forwarding them to the backends.

+
+    Please note, that Traefik needs to communicate using gRPC with the backends (h2c or HTTP/2 over TLS).

+# Configuration Details for Migrating from Traefik v2 to v3
+
+## Static Configuration Changes
+
+### SwarmMode
+
+In v3, the provider Docker has been split into 2 providers:
+
+- Docker provider (without Swarm support)
+- Swarm provider  (Swarm support only)
+
+??? example "An example usage of v2 Docker provider with Swarm"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      docker:
+        swarmMode: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.docker]
+        swarmMode=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.docker.swarmMode=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+In v3, the `swarmMode` should not be used with the Docker provider, and, to use Swarm, the Swarm provider should be used instead.
+
+??? example "An example usage of the Swarm provider"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      swarm:
+        endpoint: "tcp://127.0.0.1:2377"
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.swarm]
+        endpoint="tcp://127.0.0.1:2377"
+    ```
+
+    ```bash tab="CLI"
+    --providers.swarm.endpoint=tcp://127.0.0.1:2377
+    ```
+
+#### TLS.CAOptional
+
+Docker provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      docker:
+        tls: 
+          caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.docker.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.docker.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `tls.caOptional` option should be removed from the Docker provider static configuration.
+
+### Kubernetes Gateway API
+
+#### Experimental Channel Resources (TLSRoute and TCPRoute)
+
+In v3, the Kubernetes Gateway API provider does not enable support for the experimental channel API resources by default.
+
+##### Remediation
+
+The `experimentalChannel` option should be used to enable the support for the experimental channel API resources.
+
+??? example "An example usage of the Kubernetes Gateway API provider with experimental channel support enabled"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      kubernetesGateway:
+        experimentalChannel: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.kubernetesGateway]
+        experimentalChannel = true
+      # ...
+    ```
+
+    ```bash tab="CLI"
+    --providers.kubernetesgateway.experimentalchannel=true
+    ```
+
+### Experimental Configuration
+
+#### HTTP3
+
+In v3, HTTP/3 is no longer an experimental feature.
+It can be enabled on entry points without the associated `experimental.http3` option, which is now removed.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Experimental `http3` option"
+
+    ```yaml tab="File (YAML)"
+    experimental:
+      http3: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [experimental]
+        http3=true
+    ```
+
+    ```bash tab="CLI"
+    --experimental.http3=true
+    ```
+
+##### Remediation
+
+The `http3` option should be removed from the static configuration experimental section.
+To configure `http3`, please checkout the [entrypoint configuration documentation](../routing/entrypoints.md#http3_1).
+
+### Consul provider
+
+#### namespace
+
+The Consul provider `namespace` option was deprecated in v2 and is now removed in v3.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Consul `namespace` option"
+
+    ```yaml tab="File (YAML)"
+    consul:
+      namespace: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consul]
+        namespace=foobar
+    ```
+
+    ```bash tab="CLI"
+    --consul.namespace=foobar
+    ```
+
+##### Remediation
+
+In v3, the `namespaces` option should be used instead of the `namespace` option.
+
+??? example "An example usage of Consul `namespaces` option"
+
+    ```yaml tab="File (YAML)"
+    consul:
+      namespaces:
+        - foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consul]
+        namespaces=["foobar"]
+    ```
+
+    ```bash tab="CLI"
+    --consul.namespaces=foobar
+    ```
+
+#### TLS.CAOptional
+
+Consul provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      consul:
+        tls: 
+          caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.consul.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.consul.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `tls.caOptional` option should be removed from the Consul provider static configuration.
+
+### ConsulCatalog provider
+
+#### namespace
+
+The ConsulCatalog provider `namespace` option was deprecated in v2 and is now removed in v3.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 ConsulCatalog `namespace` option"
+
+    ```yaml tab="File (YAML)"
+    consulCatalog:
+      namespace: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consulCatalog]
+        namespace=foobar
+    ```
+
+    ```bash tab="CLI"
+    --consulCatalog.namespace=foobar
+    ```
+
+##### Remediation
+
+In v3, the `namespaces` option should be used instead of the `namespace` option.
+
+??? example "An example usage of ConsulCatalog `namespaces` option"
+
+    ```yaml tab="File (YAML)"
+    consulCatalog:
+      namespaces:
+        - foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [consulCatalog]
+        namespaces=["foobar"]
+    ```
+
+    ```bash tab="CLI"
+    --consulCatalog.namespaces=foobar
+    ```
+
+#### Endpoint.TLS.CAOptional
+
+ConsulCatalog provider `endpoint.tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the Endpoint.TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      consulCatalog:
+        endpoint:
+          tls: 
+            caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.consulCatalog.endpoint.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.consulCatalog.endpoint.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `endpoint.tls.caOptional` option should be removed from the ConsulCatalog provider static configuration.
+
+### Nomad provider
+
+#### namespace
+
+The Nomad provider `namespace` option was deprecated in v2 and is now removed in v3.
+It is now unsupported and would prevent Traefik to start.
+
+??? example "An example usage of v2 Nomad `namespace` option"
+
+    ```yaml tab="File (YAML)"
+    nomad:
+      namespace: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [nomad]
+        namespace=foobar
+    ```
+
+    ```bash tab="CLI"
+    --nomad.namespace=foobar
+    ```
+
+##### Remediation
+
+In v3, the `namespaces` option should be used instead of the `namespace` option.
+
+??? example "An example usage of Nomad `namespaces` option"
+
+    ```yaml tab="File (YAML)"
+    nomad:
+      namespaces:
+        - foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [nomad]
+        namespaces=["foobar"]
+    ```
+
+    ```bash tab="CLI"
+    --nomad.namespaces=foobar
+    ```
+
+#### Endpoint.TLS.CAOptional
+
+Nomad provider `endpoint.tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the Endpoint.TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      nomad:
+        endpoint:
+          tls: 
+            caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.nomad.endpoint.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.nomad.endpoint.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `endpoint.tls.caOptional` option should be removed from the Nomad provider static configuration.
+
+### Rancher v1 Provider
+
+In v3, the Rancher v1 provider has been removed because Rancher v1 is [no longer actively maintained](https://rancher.com/docs/os/v1.x/en/support/),
+and Rancher v2 is supported as a standard Kubernetes provider.
+
+??? example "An example of Traefik v2 Rancher v1 configuration"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      rancher: {}
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.rancher]
+    ```
+
+    ```bash tab="CLI"
+    --providers.rancher=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+Rancher 2.x requires Kubernetes and does not have a metadata endpoint of its own for Traefik to query.
+As such, Rancher 2.x users should utilize the [Kubernetes CRD provider](../providers/kubernetes-crd.md) directly.
+
+Also, all Rancher provider related configuration should be removed from the static configuration.
+
+### Marathon provider
+
+Marathon maintenance [ended on October 31, 2021](https://github.com/mesosphere/marathon/blob/master/README.md).
+In v3, the Marathon provider has been removed.
+
+??? example "An example of v2 Marathon provider configuration"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      marathon: {}
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.marathon]
+    ```
+
+    ```bash tab="CLI"
+    --providers.marathon=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+All Marathon provider related configuration should be removed from the static configuration.
+
+### HTTP Provider
+
+#### TLS.CAOptional
+
+HTTP provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      http:
+        tls: 
+          caOptional: true
+    ```
+
+    ```toml tab="File (TOML)"
+    [providers.http.tls]
+        caOptional=true
+    ```
+
+    ```bash tab="CLI"
+    --providers.http.tls.caOptional=true
+    ```
+
+##### Remediation
+
+The `tls.caOptional` option should be removed from the HTTP provider static configuration.
+
+### ETCD Provider
+
+#### TLS.CAOptional
+
+ETCD provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      etcd:
+        tls: 
+          caOptional: true

+
+### Redis Provider
+
+#### TLS.CAOptional
+
+Redis provider `tls.CAOptional` option has been removed in v3, as TLS client authentication is a server side option (see https://pkg.go.dev/crypto/tls#ClientAuthType).
+
+??? example "An example usage of the TLS.CAOptional option"
+
+    ```yaml tab="File (YAML)"
+    providers:
+      redis:
+        tls: 
+          caOptional: true
+    ```

+    ```
+
+    ```bash tab="CLI"

+
+##### Remediation

+
+### InfluxDB v1
+
+InfluxDB v1.x maintenance [ended in 2021](https://www.influxdata.com/blog/influxdb-oss-and-enterprise-roadmap-update-from-influxdays-emea/).
+In v3, the InfluxDB v1 metrics provider has been removed.
+
+??? example "An example of Traefik v2 InfluxDB v1 metrics configuration"
+
+    ```yaml tab="File (YAML)"
+    metrics:
+      influxDB: {}

+    ```toml tab="File (TOML)"
+    [metrics.influxDB]
+    ```
+
+    ```bash tab="CLI"
+    --metrics.influxDB=true
+    ```
+
+This configuration is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+All InfluxDB v1 metrics provider related configuration should be removed from the static configuration.
+
+### Pilot
+
+Traefik Pilot is no longer available since October 4th, 2022.
+
+??? example "An example of v2 Pilot configuration"
+
+    ```yaml tab="File (YAML)"
+    pilot:
+      token: foobar
+    ```
+
+    ```toml tab="File (TOML)"
+    [pilot]
+        token=foobar
+    ```
+
+    ```bash tab="CLI"
+    --pilot.token=foobar
+    ```
+
+In v2, Pilot configuration was deprecated and ineffective,
+it is now unsupported and would prevent Traefik to start.
+
+#### Remediation
+
+All Pilot related configuration should be removed from the static configuration.
+
+### Kubernetes Ingress Path Matching
+
+In v3, the Kubernetes Ingress default path matching does not support regexes anymore.
+
+#### Remediation
+
+Two levels of remediation are possible:
+
+- Interpret the default path matcher `PathPrefix` with v2 syntax.
+This can done globally for all routers with the [static configuration](#configure-the-default-syntax-in-static-configuration) or on a per-router basis by using the [traefik.ingress.kubernetes.io/router.rulesyntax](../routing/providers/kubernetes-ingress.md#annotations) annotation.
+
+- Adapt the path regex to be compatible with the Go regex syntax and change the default path matcher to use the `PathRegexp` matcher with the [`traefik.ingress.kubernetes.io/router.pathmatcher`](../routing/providers/kubernetes-ingress.md#annotations) annotation.
+
+## Operations Changes
+
+### Traefik RBAC Update
+
+In v3, the support of `TCPServersTransport` has been introduced.
+When using the KubernetesCRD provider, it is therefore necessary to update [RBAC](../reference/dynamic-configuration/kubernetes-crd.md#rbac) and [CRD](../reference/dynamic-configuration/kubernetes-crd.md) manifests.
+
+### Content-Type Auto-Detection
+
+In v3, the `Content-Type` header is not auto-detected anymore when it is not set by the backend.
+One should use the `ContentType` middleware to enable the `Content-Type` header value auto-detection.
+
+### Observability
+
+#### Open Connections Metric
+
+In v3, the open connections metric has been replaced with a global one because it was erroneously at the HTTP level, and providing misleading information.
+While previously produced at the entryPoint, router, and service levels, it is now replaced with a global metric.
+The equivalent to `traefik_entrypoint_open_connections`, `traefik_router_open_connections` and `traefik_service_open_connections` is now `traefik_open_connections`.
+
+#### Configuration Reload Failures Metrics
+
+In v3, the `traefik_config_reloads_failure_total` and `traefik_config_last_reload_failure` metrics have been suppressed since they could not be implemented.
+
+#### gRPC Metrics
+
+In v3, the reported status code for gRPC requests is now the value of the `Grpc-Status` header.
+
+#### Tracing
+
+In v3, the tracing feature has been revamped and is now powered exclusively by [OpenTelemetry](https://opentelemetry.io/ "Link to website of OTel") (OTel).
+!!! warning "Important"
+    Traefik v3 **no** longer supports direct output formats for specific vendors such as Instana, Jaeger, Zipkin, Haystack, Datadog, and Elastic.
+    Instead, it focuses on pure OpenTelemetry implementation, providing a unified and standardized approach for observability.
+
+Here are two possible transition strategies:
+
+1. OTLP Ingestion Endpoints:
+
+    Most vendors now offer OpenTelemetry Protocol (OTLP) ingestion endpoints.
+    You can seamlessly integrate Traefik v3 with these endpoints to continue leveraging tracing capabilities.
+
+2. Legacy Stack Compatibility:
+
+    For legacy stacks that cannot immediately upgrade to the latest vendor agents supporting OTLP ingestion,
+    using OpenTelemetry (OTel) collectors with appropriate exporters configuration is a viable solution.
+    This allows continued compatibility with the existing infrastructure.
+
+Please check the [OpenTelemetry Tracing provider documention](../observability/tracing/opentelemetry.md) for more information.
+
+#### Internal Resources Observability
+
+In v3, observability for internal routers or services (e.g.: `ping@internal`) is disabled by default.
+To enable it one should use the new `addInternals` option for AccessLogs, Metrics or Tracing.
+Please take a look at the observability documentation for more information:
+
+- [AccessLogs](../observability/access-logs.md#addinternals)
+- [Metrics](../observability/metrics/overview.md#addinternals)
+- [Tracing](../observability/tracing/overview.md#addinternals)
+
+#### Access logs
+
+In v3, the `ServiceURL` field is not an object anymore but a string representation.
+An update may be required if you index access logs.
+
+## Dynamic Configuration Changes
+
+### Router Rule Matchers
+
+In v3, a new rule matchers syntax has been introduced for HTTP and TCP routers.
+The default rule matchers syntax is now the v3 one, but for backward compatibility this can be configured.
+The v2 rule matchers syntax is deprecated and its support will be removed in the next major version.
+For this reason, we encourage migrating to the new syntax.
+
+By default, the `defaultRuleSyntax` static option is automatically set to `v3`, meaning that the default rule is the new one.
+
+#### New V3 Syntax Notable Changes
+
+The `Headers` and `HeadersRegexp` matchers have been renamed to `Header` and `HeaderRegexp` respectively.
+
+`PathPrefix` no longer uses regular expressions to match path prefixes.
+
+`QueryRegexp` has been introduced to match query values using a regular expression.
+
+`HeaderRegexp`, `HostRegexp`, `PathRegexp`, `QueryRegexp`, and `HostSNIRegexp` matchers now uses the [Go regexp syntax](https://golang.org/pkg/regexp/syntax/).
+
+All matchers now take a single value (except `Header`, `HeaderRegexp`, `Query`, and `QueryRegexp` which take two)
+and should be explicitly combined using logical operators to mimic previous behavior.
+
+`Query` can take a single value to match is the query value that has no value (e.g. `/search?mobile`).
+
+`HostHeader` has been removed, use `Host` instead.
+
+#### Remediation
+
+##### Configure the Default Syntax In Static Configuration
+
+The default rule matchers syntax is the expected syntax for any router that is not self opt-out from this default value.
+It can be configured in the static configuration.
+
+??? example "An example configuration for the default rule matchers syntax"
+
+    ```yaml tab="File (YAML)"
+    # static configuration
+    core:
+      defaultRuleSyntax: v2
+    ```
+
+    ```toml tab="File (TOML)"
+    # static configuration
+    [core]
+        defaultRuleSyntax="v2"
+    ```
+
+    ```bash tab="CLI"
+    # static configuration
+    --core.defaultRuleSyntax=v2
+    ```
+
+##### Configure the Syntax Per Router
+
+The rule syntax can also be configured on a per-router basis.
+This allows to have heterogeneous router configurations and ease migration.
+
+??? example "An example router with syntax configuration"
+
+```yaml tab="Docker & Swarm"
+labels:
+  - "traefik.http.routers.test.ruleSyntax=v2"
+```
+
+```yaml tab="Kubernetes"
+apiVersion: traefik.io/v1alpha1
+kind: IngressRoute
+metadata:
+  name: test.route
+  namespace: default
+
+spec:
+  routes:
+    - match: PathPrefix(`/foo`, `/bar`)
+      syntax: v2
+      kind: Rule
+```
+
+```yaml tab="Consul Catalog"
+- "traefik.http.routers.test.ruleSyntax=v2"
+```
+
+```yaml tab="File (YAML)"
+http:
+  routers:
+    test:
+      ruleSyntax: v2
+```
+
+```toml tab="File (TOML)"
+[http.routers]
+  [http.routers.test]
+    ruleSyntax = "v2"
+```
+
+### IPWhiteList
+
+In v3, we renamed the `IPWhiteList` middleware to `IPAllowList` without changing anything to the configuration. 
+
+### Deprecated Options Removal
+
+- The `tracing.datadog.globaltag` option has been removed.
+- The `tls.caOptional` option has been removed from the ForwardAuth middleware, as well as from the HTTP, Consul, Etcd, Redis, ZooKeeper, Consul Catalog, and Docker providers.
+- `sslRedirect`, `sslTemporaryRedirect`, `sslHost`, `sslForceHost` and `featurePolicy` options of the Headers middleware have been removed.
+- The `forceSlash` option of the StripPrefix middleware has been removed.
+- The `preferServerCipherSuites` option has been removed.
+
+### TCP LoadBalancer `terminationDelay` option
+
+The TCP LoadBalancer `terminationDelay` option has been removed.
+This option can now be configured directly on the `TCPServersTransport` level, please take a look at this [documentation](../routing/services/index.md#terminationdelay)
+
+### Kubernetes CRDs API Group `traefik.containo.us`
+
+In v3, the Kubernetes CRDs API Group `traefik.containo.us` has been removed. 
+Please use the API Group `traefik.io` instead.
+
+### Kubernetes Ingress API Group `networking.k8s.io/v1beta1`
+
+In v3, the Kubernetes Ingress API Group `networking.k8s.io/v1beta1` ([removed since Kubernetes v1.22](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#ingress-v122)) support has been removed.
+
+Please use the API Group `networking.k8s.io/v1` instead.
+
+### Traefik CRD API Version `apiextensions.k8s.io/v1beta1`
+
+In v3, the Traefik CRD API Version `apiextensions.k8s.io/v1beta1` ([removed since Kubernetes v1.22](https://kubernetes.io/docs/reference/using-api/deprecation-guide/#customresourcedefinition-v122)) support has been removed.
+
+Please use the CRD definition with the API Version `apiextensions.k8s.io/v1` instead.

+
+# Migration Guide: From v2 to v3
+
+How to Migrate from Traefik v2 to Traefik v3.
+{: .subtitle }
+
+With Traefik v3, we are introducing a streamlined transition process from v2. Minimal breaking changes have been made to specific options in the [static configuration](./v2-to-v3-details.md#static-configuration-changes "Link to static configuration changes"), and we are ensuring backward compatibility with v2 syntax in the [dynamic configuration](./v2-to-v3-details.md#dynamic-configuration-changes "Link to dynamic configuration changes"). This will offer a gradual path for adopting the v3 syntax, allowing users to progressively migrate their Kubernetes ingress resources, Docker labels, etc., to the new format.
+
+Here are the steps to progressively migrate from Traefik v2 to v3:
+
+1. [Prepare configurations and test v3](#step-1-prepare-configurations-and-test-v3)
+1. [Migrate production instances to Traefik v3](#step-2-migrate-production-instances-to-traefik-v3)
+1. [Progressively migrate dynamic configuration](#step-3-progressively-migrate-dynamic-configuration)
+
+## Step 1: Prepare Configurations and Test v3
+
+Check the changes in [static configurations](./v2-to-v3-details.md#static-configuration-changes "Link to static configuration changes") and [operations](./v2-to-v3-details.md#operations-changes "Link to operations changes") brought by Traefik v3.
+Modify your configurations accordingly.
+
+Then, add the following snippet to the static configuration:
+
+```yaml
+# static configuration
+core:
+  defaultRuleSyntax: v2
+```
+
+This snippet in the static configuration makes the [v2 format](../migration/v2-to-v3-details.md#configure-the-default-syntax-in-static-configuration "Link to configure default syntax in static config") the default rule matchers syntax.
+
+Start Traefik v3 with this new configuration to test it.
+
+If you don’t get any error logs while testing, you are good to go!
+Otherwise, follow the remaining migration options highlighted in the logs.
+
+Once your Traefik test instances are starting and routing to your applications, proceed to the next step.
+
+## Step 2: Migrate Production Instances to Traefik v3
+
+We strongly advise you to follow a progressive migration strategy ([Kubernetes rolling update mechanism](https://kubernetes.io/docs/tutorials/kubernetes-basics/update/update-intro/ "Link to the Kubernetes rolling update documentation"), for example) to migrate your production instances to v3.
+
+!!! Warning
+    Ensure you have a [real-time monitoring solution](https://traefik.io/blog/capture-traefik-metrics-for-apps-on-kubernetes-with-prometheus/ "Link to the blog on capturing Traefik metrics with Prometheus") for your ingress traffic to detect issues instantly.
+
+During the progressive migration, monitor your ingress traffic for any errors. Be prepared to rollback to a working state in case of any issues.
+
+If you encounter any issues, leverage debug and access logs provided by Traefik to understand what went wrong and how to fix it.
+
+Once every Traefik instance is updated, you will be on Traefik v3!
+
+## Step 3: Progressively Migrate Dynamic Configuration
+
+!!! info
+    This step can be done later in the process, as Traefik v3 is compatible with the v2 format for [dynamic configuration](./v2-to-v3-details.md#dynamic-configuration-changes "Link to dynamic configuration changes").
+    Enable Traefik logs to get some help if any deprecated option is in use.
+
+Check the changes in [dynamic configuration](./v2-to-v3-details.md#dynamic-configuration-changes "Link to dynamic configuration changes").
+
+Then, progressively [switch each router to the v3 syntax](./v2-to-v3-details.md#configure-the-syntax-per-router "Link to configuring the syntax per router").
+
+Test and update each Ingress resource and ensure that ingress traffic is not impacted.
+
+Once a v3 Ingress resource migration is validated, deploy the resource and delete the v2 Ingress resource.
+Repeat it until all Ingress resources are migrated.
+
+Now, remove the following snippet added to the static configuration in Step 1:
+
+```yaml
+# static configuration
+core:
+  defaultRuleSyntax: v2
+```
+
+You are now fully migrated to Traefik v3 🎉

+
+## v3.0 to v3.1
+
+### Kubernetes Provider RBACs
+
+Starting with v3.1, the Kubernetes Providers now use the [EndpointSlices API](https://kubernetes.io/docs/concepts/services-networking/endpoint-slices/) (Kubernetes >=v1.21) to discover service endpoint addresses.
+It also brings NodePort load-balancing which requires Nodes resources lookup.
+
+Therefore, in the corresponding RBACs (see [KubernetesIngress](../routing/providers/kubernetes-ingress.md#configuration-example), [KubernetesCRD](../reference/dynamic-configuration/kubernetes-crd.md#rbac), and [KubernetesGateway](../reference/dynamic-configuration/kubernetes-gateway-rbac.yml) provider RBACs):
+
+- the `endpoints` right has to be removed and the following `endpointslices` right has to be added:
+
+```yaml
+  ... 
+  - apiGroups:
+      - discovery.k8s.io
+    resources:
+      - endpointslices
+    verbs:

+      - list
+      - watch
+  ...
+```
+
+#### Gateway API: KubernetesGateway Provider
+
+In v3.1, the KubernetesGateway Provider is no longer an experimental feature.
+It can be enabled without the associated `experimental.kubernetesgateway` option, which is now deprecated.
+
+??? example "An example of the experimental `kubernetesgateway` option"
+
+    ```yaml tab="File (YAML)"

+        kubernetesgateway=true
+    ```
+
+    ```bash tab="CLI"
+    --experimental.kubernetesgateway=true
+    ```
+
+##### Remediation
+
+The `kubernetesgateway` option should be removed from the experimental section of the static configuration.
+To configure `kubernetesgateway`, please check out the [KubernetesGateway Provider documentation](../providers/kubernetes-gateway.md).
+
+## v3.1.0 to v3.1.1
+
+### IngressClass Lookup
+
+The Kubernetes Ingress provider option `disableIngressClassLookup` has been deprecated in v3.1.1, and will be removed in the next major version.
+Please use the `disableClusterScopeResources` option instead to avoid cluster scope resources discovery (IngressClass, Nodes).
+
+## v3.1 to v3.2
+
+### Kubernetes CRD Provider
+
+Starting with v3.2, the CRDs has been updated on [TraefikService](../../routing/services#mirroring-service) (PR [#11032](https://github.com/traefik/traefik/pull/11032)), on [RateLimit](../../middlewares/http/ratelimit) & [InFlightReq](../../middlewares/http/inflightreq) middlewares (PR [#9747](https://github.com/traefik/traefik/pull/9747)) and on [Compress](../../middlewares/http/compress) middleware (PR [#10943](https://github.com/traefik/traefik/pull/10943)).
+
+This update adds only new optional fields.
+CRDs can be updated with this command:
+
+```shell
+kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.3/docs/content/reference/dynamic-configuration/kubernetes-crd-definition-v1.yml
+```
+
+### Kubernetes Gateway Provider Standard Channel
+
+Starting with v3.2, the Kubernetes Gateway Provider now supports [GRPCRoute](https://gateway-api.sigs.k8s.io/api-types/grpcroute/).
+
+Therefore, in the corresponding RBACs (see [KubernetesGateway](../reference/dynamic-configuration/kubernetes-gateway-rbac.yml) provider RBACs),
+the `grcroutes` and `grpcroutes/status` rights have to be added.
+
+```yaml

+    resources:
+      - grpcroutes/status
+    verbs:
+      - update
+  ...
+```
+
+### Kubernetes Gateway Provider Experimental Channel
+
+!!! warning "Breaking changes"
+
+    Because of a breaking change introduced in Kubernetes Gateway [v1.2.0-rc1](https://github.com/kubernetes-sigs/gateway-api/releases/tag/v1.2.0-rc1),
+    Traefik v3.3 only supports Kubernetes Gateway v1.2.x when experimental channel features are enabled.
+
+Starting with v3.2, the Kubernetes Gateway Provider now supports [BackendTLSPolicy](https://gateway-api.sigs.k8s.io/api-types/backendtlspolicy/).
+
+Therefore, in the corresponding RBACs (see [KubernetesGateway](../reference/dynamic-configuration/kubernetes-gateway-rbac.yml) provider RBACs),
+the `backendtlspolicies` and `backendtlspolicies/status` rights have to be added.
+
+```yaml
+  ...
+  - apiGroups:
+      - ""

+```
+
+## v3.2.1
+
+### X-Forwarded-Prefix
+
+In `v3.2.1`, the `X-Forwarded-Prefix` header is now handled like the other `X-Forwarded-*` headers: Traefik removes it when it's sent from an untrusted source.
+Please refer to the Forwarded headers [documentation](../routing/entrypoints.md#forwarded-headers) for more details.
+
+## v3.2.2
+
+### Swarm Provider
+
+In `v3.2.2`, the `traefik.docker.network` and `traefik.docker.lbswarm` labels have been deprecated,
+please use the `traefik.swarm.network` and `traefik.swarm.lbswarm` labels instead.
+
+## v3.2 to v3.3
+
+### ACME DNS Certificate Resolver
+
+In `v3.3`, the `acme.dnsChallenge.delaybeforecheck` and `acme.dnsChallenge.disablepropagationcheck` options of the ACME certificate resolver are deprecated, 
+please use respectively `acme.dnsChallenge.propagation.delayBeforeChecks` and `acme.dnsChallenge.propagation.disableChecks` options instead.
+
+### Tracing Global Attributes
+
+In `v3.3`, the `tracing.globalAttributes` option has been deprecated, please use the `tracing.resourceAttributes` option instead.
+The `tracing.globalAttributes` option is misleading as its name does not reflect the operation of adding resource attributes to be sent to the collector,
+and will be removed in the next major version.
+
+## v3.3.4
+
+### OpenTelemetry Request Duration metric
+
+In `v3.3.4`, the OpenTelemetry Request Duration metric (named `traefik_(entrypoint|router|service)_request_duration_seconds`) unit has been changed from milliseconds to seconds.
+To be consistent with the naming and other metrics providers, the metric now reports the duration in seconds.
+
+## v3.3.5
+
+### Compress Middleware
+
+In `v3.3.5`, the compress middleware `encodings` option default value is now `gzip, br, zstd`. 
+This change helps the algorithm selection to favor the `gzip` algorithm over the other algorithms.
+
+It impacts requests that do not specify their preferred algorithm,
+or has no order preference, in the `Accept-Encoding` header.
+
+## v3.3.6
+
+### Request Path Sanitization
+
+Since `v3.3.6`, the incoming request path is now cleaned before being used to match the router rules and sent to the backends.
+Any `/../`, `/./` or duplicate slash segments in the request path is interpreted and/or collapsed.
+
+If you want to disable this behavior, you can set the [`sanitizePath` option](../reference/install-configuration/entrypoints.md#sanitizepath) to `false` in the entryPoint HTTP configuration.
+This can be useful when dealing with legacy clients that are not url-encoding data in the request path.
+For example, as base64 uses the “/” character internally,
+if it's not url encoded,
+it can lead to unsafe routing when the `sanitizePath` option is set to `false`.
+
+!!! warning "Security"
+
+    Setting the `sanitizePath` option to `false` is not safe.
+    Ensure every request is properly url encoded instead.
+
+## v3.3 to v3.4
+
+### Kubernetes CRD Provider
+
+#### Load-Balancing
+
+In `v3.4`, the HTTP service definition has been updated.
+The strategy field now supports two new values: `wrr` and `p2c` (please refer to the [HTTP Services Load Balancing documentation](../../routing/services/#load-balancing-strategy) for more details).
+
+CRDs can be updated with this command:
+
+```shell
+kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v3.4/docs/content/reference/dynamic-configuration/kubernetes-crd-definition-v1.yml
+```
+
+Please note that the `RoundRobin` strategy value is now deprecated, but still supported and equivalent to `wrr`, and will be removed in the next major release.
+
+#### ServersTransport CA Certificate
+
+In `v3.4`, a new `rootCAs` option has been added to the `ServersTransport` and `ServersTransportTCP` CRDs.
+It allows the configuration of CA certificates from both `ConfigMaps` and `Secrets`,
+and replaces the `rootCAsSecrets` option, as shown below:
+
+```yaml
+---
+apiVersion: traefik.io/v1alpha1
+kind: ServersTransport
+metadata:
+  name: foo
+  namespace: bar
+spec:
+  rootCAs:
+    - configMap: ca-config-map
+    - secret: ca-secret
+      
+---      
+apiVersion: traefik.io/v1alpha1
+kind: ServersTransportTCP
+metadata:
+  name: foo
+  namespace: bar
+spec:
+  rootCAs:
+    - configMap: ca-config-map
+    - secret: ca-secret
+```
+
+The `rootCAsSecrets` option, which allows only `Secrets` references,
+is still supported, but is now deprecated,
+and will be removed in the next major release.
+
+### Rule Syntax
+
+In `v3.4.0`, the `core.defaultRuleSyntax` static configuration option and the `ruleSyntax` router option have been deprecated,
+and will be removed in the next major version.
+
+This `core.defaultRuleSyntax` option was used to switch between the v2 and v3 syntax for the router's rules,
+and to help with the migration from v2 to v3.
+
+The `ruleSyntax` router's option was used to override the default rule syntax for a specific router.
+
+In preparation for the next major release, please remove any use of these two options and use the v3 syntax for writing the router's rules.

 # Metrics
 
-Traefik supports these metrics backends:
+Traefik provides metrics in the [OpenTelemetry](./opentelemetry.md) format as well as the following vendor specific backends:
 
 - [Datadog](./datadog.md)
-- [InfluxDB](./influxdb.md)
 - [InfluxDB2](./influxdb2.md)
 - [Prometheus](./prometheus.md)
 - [StatsD](./statsd.md)
 
+Traefik Proxy hosts an official Grafana dashboard for both [on-premises](https://grafana.com/grafana/dashboards/17346)
+and [Kubernetes](https://grafana.com/grafana/dashboards/17347) deployments.
+
+## Common Options
+
+### `addInternals`
+
+_Optional, Default="false"_
+
+Enables metrics for internal resources (e.g.: `ping@internals`).
+
+```yaml tab="File (YAML)"
+metrics:
+  addInternals: true
+```
+
+```toml tab="File (TOML)"
+[metrics]

+
+# Overview
+
+Traefik’s observability features include logs, access logs, metrics, and tracing. You can configure these options globally or at more specific levels, such as per router or per entry point.
+
+## Configuration Example
+
+Enable access logs, metrics, and tracing globally
+
+```yaml tab="File (YAML)"
+accessLog: {}
+
+metrics:
+  otlp: {}
+
+tracing: {}
+```
+
+```yaml tab="File (TOML)"
+[accessLog]
+
+[metrics]
+  [metrics.otlp]
+
+[tracing]
+```
+
+```bash tab="CLI"
+--accesslog=true
+--metrics.otlp=true
+--tracing=true
+```
+
+You can disable access logs, metrics, and tracing for a specific entrypoint attached to a router:
+
+```yaml tab="File (YAML)"
+# Static Configuration
+entryPoints:
+  EntryPoint0:
+    address: ':8000/udp'
+    observability:
+      accessLogs: false
+      tracing: false
+      metrics: false
+```
+
+```toml tab="File (TOML)"
+# Static Configuration
+[entryPoints.EntryPoint0]
+  address = ":8000/udp"
+
+    [entryPoints.EntryPoint0.observability]

+
+## Configuration Options
+
+### Logs
+
+Traefik logs informs about everything that happens within Traefik (startup, configuration, events, shutdown, and so on).
+
+Read the [Logs documentation](./logs.md) to learn how to configure it.
+
+### Access Logs
+
+Access logs are a key part of observability in Traefik.
+
+They are providing valuable insights about incoming traffic, and allow to monitor it.
+The access logs record detailed information about each request received by Traefik,
+including the source IP address, requested URL, response status code, and more.
+
+Read the [Access Logs documentation](./access-logs.md) to learn how to configure it.
+
+### Metrics
+
+Traefik offers a metrics feature that provides valuable insights about the performance and usage.
+These metrics include the number of requests received, the requests duration, and more.
+
+On top of supporting metrics in the OpenTelemetry format, Traefik supports the following vendor specific metrics systems: Prometheus, Datadog, InfluxDB 2.X, and StatsD.
+
+Read the [Metrics documentation](./metrics/overview.md) to learn how to configure it.
+
+### Tracing
+
+The Traefik tracing system allows developers to gain deep visibility into the flow of requests through their infrastructure.
+
+Traefik provides tracing information in the OpenTelemery format.
+
+Read the [Tracing documentation](./tracing/overview.md) to learn how to configure it.

+
+!!! info "Default protocol"
+
+    The OpenTelemetry trace exporter will export traces to the collector using HTTPS by default to https://localhost:4318/v1/traces, see the [gRPC Section](#grpc-configuration) to use gRPC.
+
+!!! info "Trace sampling"
+
+	By default, the OpenTelemetry trace exporter will sample 100% of traces.  
+	See [OpenTelemetry's SDK configuration](https://opentelemetry.io/docs/reference/specification/sdk-environment-variables/#general-sdk-configuration) to customize the sampling strategy.
+
+!!! info "Propagation"
+    
+    Traefik supports the `OTEL_PROPAGATORS` env variable to set up the propragators. The supported propagators are:
+
+    - tracecontext (default)
+    - baggage (default)
+    - b3

+### Custom API Base Path
+
+As shown above, by default Traefik exposes its API and Dashboard under the `/` base path,
+which means that respectively the API is served under the `/api` path,
+and the dashboard under the `/dashboard` path.
+
+However, it is possible to configure this base path:
+
+```yaml tab="File (YAML)"
+api:
+  # Customizes the base path:
+  # - Serving API under `/traefik/api`
+  # - Serving Dashboard under `/traefik/dashboard`
+  basePath: /traefik

+
 ## Insecure Mode
 
+!!! warning "Please note that this mode is incompatible with the [custom API base path option](#custom-api-base-path)."
+
 When _insecure_ mode is enabled, one can access the dashboard on the `traefik` port (default: `8080`) of the Traefik instance,
 at the following URL: `http://<Traefik IP>:8080/dashboard/` (trailing slash is mandatory).
