+### Enabling Xdebug for the CLI
+
+After enabling Xdebug, the CLI will not load the module by default.
+To load it, you can set the `PHP_INI_SCAN_DIR` environment variable to the specific Xdebug-enable config directory:
+
+```console
+app@abcdef-example-magweb-cmbl:~$ export PHP_VERSION=$(jq -r .php_version /etc/hypernode/app.json)
+app@abcdef-example-magweb-cmbl:~$ export PHP_INI_SCAN_DIR=/etc/php-debug/$PHP_VERSION/cli/conf.d/
+app@abcdef-example-magweb-cmbl:~$ php -m | grep xdebug
+xdebug
+```
