!!! note 

   If you use a `phpdoc.dist.xml` you can place it anywhere in your repository. But don't forget to edit `PHPDOC_CONFIG_FILE`, so the job knows where the config file is.

!!! info 

    This job allows you to use a configuration file named `phpdoc.dist.xml` (see [syntax](https://docs.phpdoc.org/3.0/guide/references/configuration.html)). 

    By default PHPDoc will search for a configuration file in `PROJECT_ROOT` and will use it if the file does exist. But you can customize the location to `phpdoc.dist.xml` by editing `PHPDOC_CONFIG_FILE`.
