+# Setting `GOPATH`
+
+The `GOPATH` environment variable specifies the location of your workspace. If no `GOPATH` is set, it is assumed to be `$HOME/go` on Unix systems and `%USERPROFILE%\go` on Windows. If you want to use a custom location as your workspace, you can set the `GOPATH` environment variable. This page explains how to set this variable on various platforms.

+
+# Unix systems
+
+`GOPATH` can be any directory on your system. In Unix examples, we will set it to `$HOME/go` (since Go 1.8, it's a default `GOPATH` on Unix-like systems). Note that `GOPATH` must not be the same path as your Go installation. Another common setup is to set `GOPATH=$HOME`.
+
+## Bash
+
+Edit your `~/.bash_profile` to add the following line:
+```bash
+export GOPATH=$HOME/go
+```
+
+Save and exit your editor. Then, source your `~/.bash_profile`.
+```bash
+source ~/.bash_profile
+```
+
+> Note: Set the GOBIN path to generate a binary file when `go install` is run.
+> ```bash
+> export GOBIN=$HOME/go/bin
+> ```
+
+## Zsh
+
+Edit your `~/.zshrc` file to add the following line:
+
+```bash
+export GOPATH=$HOME/go
+```
+Save and exit your editor. Then, source your `~/.zshrc`.
+```bash
+$ source ~/.zshrc
+```
+
+## fish
+
+```bash
+set -x -U GOPATH $HOME/go
+```
+> The `-x` is used to specify that this variable should be exported
+> and the `-U` makes this a universal variable, available to all sessions and
+> persistent
+
+To set the GOBIN path:
+
+```bash
+set -x -U GOBIN $GOPATH/bin
+```
+
+# Windows
+
+Your workspace can be located wherever you like,
+but we'll use `C:\go-work` in this example.
+
+__NOTE:__ that `GOPATH` must not be the same path as your Go installation.
+
+* Create folder at `C:\go-work`.
+* Right click on "Start" and click on "Control Panel". Select "System and Security", then click on "System".
+* From the menu on the left, select the "Advanced systems settings".
+* Click the "Environment Variables" button at the bottom.
+* Click "New" from the "User variables" section.
+* Type `GOPATH` into the "Variable name" field.
+* Type `C:\go-work` into the "Variable value" field.
+* Click OK.
+
+## Windows 10
+There is a faster way to edit `Environment Variables` with search
+* Left click on "Search" and type `env` or `environment`. select `Edit environment variables for your account`
+* and follow step above
