 To install a non-stable version of Symfony, use the `STABILITY` environment variable during the build.
 The value must be [a valid Composer stability option](https://getcomposer.org/doc/04-schema.md#minimum-stability)) .
 
 For instance, use the following command to use the `master` branch of Symfony:
