+## Debugging your Docker setup
+
+Even when running your Invoice Ninja setup with Docker - errors can occur. Depending on where the error happens - the webserver, Invoice Ninja or the database - different log files can be responsible. 
+
+### Show logs without `docker-compose`
+
+If you are not running the `docker-compose` you first need to find the container id for your php container with `docker ps`. Then you can run
+
+```shell
+docker logs -f <CONTAINER NAME>
+```
+
+This gives you a constant output of the log files for the php container.
+
+### Show logs with `docker-compose`
+
+If you are running the `docker-compose` setup you can output all logs, from all containers, with the following command
+
+```shell
+docker-compose logs -f
+```
+
+If you better want a physical log file in in your `storage/logs` folder, just remove this line `-e LOG=errorlog` from the [usage](#usage) command or change it to `-e LOG=single`. Both works.
