@@ -58,4 +70,50 @@ If the registry succeed, it will run immediately. Next time, you could run the r
 
 ```bash
 ./act_runner daemon
-```
+```
+
+### Configuration
+
+You can also configure the runner with a configuration file.
+The configuration file is a YAML file, you can generate a sample configuration file with `./act_runner generate-config`.
+
+```bash
+./act_runner generate-config > config.yaml
+```
+
+You can specify the configuration file path with `-c`/`--config` argument.
+
+```bash
+./act_runner -c config.yaml register # register with config file
+./act_runner -c config.yaml deamon # run with config file
+```
+
+### Run a docker container
+
+```sh
+docker run -e GITEA_INSTANCE_URL=http://192.168.8.18:3000 -e GITEA_RUNNER_REGISTRATION_TOKEN=<runner_token> -v /var/run/docker.sock:/var/run/docker.sock -v $PWD/data:/data --name my_runner gitea/act_runner:nightly
+```
+
+The `/data` directory inside the docker container contains the runner API keys after registration.
+It must be persisted, otherwise the runner would try to register again, using the same, now defunct registration token.
+
+### Running in docker-compose
+
+```yml
+...
+  gitea:
+    image: gitea/gitea
+    ...
+
+  runner:
+    image: gitea/act_runner

+    volumes:
