+## Usage
+The easiest method is to use the *ready-to-use* image from dockerhub, using `docker compose`. Create a file called `docker-compose.yml` and add the following content:
+
+```yaml
+services:
+  opentracker:
+    container_name: opentracker
+    image: mikognn/opentracker
+    ports:
+      - 6969:6969
+    volumes:
+      - ./config:/config
+```
+
+then create a `config` directory in the same folder as the `.yml` file and add the `opentracker.conf`. You can find a fully fletched *(and documented)* version of it in the [`opentracker.conf.sample`][config] file.
+
+### Build it yourself
+You can also clone my [repo][repo] and run `docker compose up` from within. This will build the container on your machine.
+
+Just run
+```bash
+	git clone --recursive https://git.mike-ochmann.de/miko/opentracker.git
+	cd opentracker
+	cp config/opentracker.conf.sample config/opentracker.conf
+	sudo docker compose up -d
+```

 The license is not really clear to me. It may be GPL or "beer ware license" or
 a combination of both. I will not really give any license information because
 of that.
