 # Debugging Drupal Code
 
+Debugging PHP can be a game changer in Drupal development. In the context of L3D
+in combination with the composer plugin [Docker4Drupal](/composer/plugin/d4d)
+this is provided out of the box and configured very easily. We describe the
+steps for PhpStorm, but other IDEs should be very similar.
+
+As XDebug comes with a performance hit, it is turned off by default. When you
+need it, simply call `ahoy debug on` in you L3D container of the project you
+want to debug and the scripts will reconfigure the PHP container and refresh
+it with a few seconds. When you've finished debugging, you may want to turn it
+off again with `ahoy debug off`.
+
+XDebug version 3 connects to port 9003 of your IDE and PhpStorm is preconfigured
+by default to list on that port.

 ## Add a PHP Server
 
 First, you have to set up a Drupal environment with the tool [l3d](../docker/l3d/index.md). The tool is

-XDebug version 3 connects to port 9003 of your IDE and PhpStorm is preconfigured

-
-You can then just enable debugging in PhpStorm and wait for the first request
-which will prompt you to configure the details. Or you configure actively the
-debug configuration:

-
-The name and the server name should both be called `Docker`. And the mapping
-needs to be configured from your project root directory on your host to the
-path `/var/www/html` in the container.
-
-With this setup, you can debug both web requests coming from the browser and
-CLI commands for PHP which is executed inside the PHP container like e.g.
-drush - all with the same setup.

 ## Using MailPit
 
 When using the [Docker4Drupal](../../composer/plugin/d4d/index.md), a MailPit service will be configured automatically by default.
