+This will clone the repository identified by OWNER/REPO into `$HOME/github/$OWNER/$REPO`.
 
 Example:
 
 `gh get britter/gh-get` will clone this respository into `~/workspace/britter/gh-get`
 
+## Configuration
+
+There are two environment variables that control the location gh-get clones repositories to:
+
+- `GH_GET_FOLDER`: The name of the folder inside the user home that repositories are cloned into. The defaults to `github` which means repositories are cloned into `$HOME/github`. If you prefer a different folder name or path inside your user home, configure this variable.
+- `GH_GET_ROOT`: The full path to to the folder that repositories are cloned into. This defaults to `$HOME/$GH_GET_FOLDER`. Change this is you want repositories to be cloned to a location _outside_ your user home.
