 A *module* is a collection of related Go packages that are versioned together as a single unit. Most often, a single version-control repository corresponds exactly to a single module, but alternatively a single version-control repository can hold multiple modules.
 
-Modules must be [semantically versioned](https://semver.org/) in the form `v(major).(minor).(patch)`, such as  `v0.1.0`, `v1.2.3`, or `v3.0.1`. The leading `v` is required. If using Git, [tag](https://git-scm.com/book/en/v2/Git-Basics-Tagging) released commits with their versions.
