  ### <a id="engine-configurations"></a> HTTPD, Nginx and PHP configuration
  
  The buildpack automatically configures HTTPD, Nginx and PHP for your application.  This section explains how to modify the configuration.
  
  The `.bp-config` directory in your application can contain configuration overrides for these components. Name the directories `httpd`, `nginx`, and `php`.
