+# Quick reference
+
+The images base on the official php(-fpm) images from docker. See [docker hub](https://hub.docker.com/_/php/)
+for the official details. We use only the debian (stretch) versions.
+
+The following changes were made:
+
+* Increased many of the default limits (execution time, upload size, …)
+* Enabled logging on stderr, so errors are visible in the docker logs
+* Installed composer (from [composer:latest](https://hub.docker.com/_/composer/))
+
+See our [apache images](https://git.team23.de/docker/apache) ("php") for usage example.
+
+# Debugging using xdebug
+
+xdebug in installed by default, but not enabled. A script `team23-docker-php-enable-xdebug.sh` is provided to
+enable xdebug. It is then configured this way:
+```ini
+xdebug.remote_port=9000
+xdebug.remote_enable=1
+xdebug.remote_connect_back=1
+```
+
+This allows for remote xdebug connections.
+
+Example Dockerfile to enable xdebug:
+
+```dockerfile
+FROM docker.team23.de/docker/php-minimal:X.Y
+
+RUN team23-docker-php-enable-xdebug.sh
+```
+
+### Alternatively enable xdebug using environment variables
+
+docker-compose.yml:
+
+```yaml
+version: "3.0"
+
+services:
+  php:
+    image: docker.team23.de/docker/php-minimal:X.Y
+    environment:
+      TEAM23_DOCKER_PHP_ENABLE_XDEBUG: 1
+```
+
+Of just start the container using `docker … -e TEAM23_DOCKER_PHP_ENABLE_XDEBUG=1 …` in your shell.
