 The most simple setup just creates a volume and a network and starts the `gitea/gitea:latest`
 image as a service. Since there is no database available one can be initialized using SQLite3.
 Create a directory like `gitea` and paste the following content into a file named `docker-compose.yml`.

+If you don't give the volume correct permissions, the container may not start.
