 - Accepts `lowest` to set up the lowest supported PHP version.
 - Accepts `highest` or `latest` to set up the latest stable PHP version.
 - Accepts `nightly` to set up a nightly build from the master branch of PHP.
+- Accepts `pre-installed` to set up the highest pre-installed PHP version. You can combine this with `update: true` to update the pre-installed PHP version.
 - Accepts the format `d.x`, where `d` is the major version. For example `5.x`, `7.x` and `8.x`.  
 - See [PHP support](#tada-php-support) for the supported PHP versions.
