- The Drupal project's codebase must be writable in order to use Automatic Updates. This includes Drupal, modules, themes and the Composer dependencies in the vendor directory. This makes Automatic Updates incompatible with some hosting platforms.
- The Composer executable must be in the PATH of the web server. If the Composer executable cannot be found the location can be set by adding
`$config['package_manager.settings']['executables']['composer'] = '/path/to/composer';` in `settings.php`
### Limitations
- Drupal multi-site installations are not supported.
- Automatic Updates does not support version control such as Git. It is the responsibility of site administrators to commit any updates to version control if needed.
