 Laravel requires a URL to be set in the `.env` file in the project root. This is done for you automatically when the workspace is initialized. The URL set in the `.env` file contains the server port. so if you want to properly serve Laravel pages from a server other than the default server you initialized the project with then will need to change the values for APP_URL and ASSET_URL accordingly.
 
+### Changing the Laravel Version
+In `starter.ini` there is a directive to change the version of Laravel. 
+
+**Important**:
+- By default `gitpod-laravel-starter` uses the most recent version of Laravel. Currently this is version `8.*`
+- There are exactly three supported values for the Laravel version directive: `8.*`, `7.*`, and `6.*` 
+- Laravel will always use the most recent/stable minor and patch version for any major version
+
+**Caveats**:
+ - Upgrading or downgrading Laravel once Laravel scaffolding files have been saved to your repository is not advised and should not be done
+ - Attempts to upgrade will will result in an automatic downgrade and could cause instability
+ - Attempts to downgrade will be ignored and could cause instability
