 This will create a docker image for running a gitlab runner on Alpine Linux on
 all the architectures that Alpine Linux supports.
+
+## Starting the runner
+
+To run the container, 1 required and 2 optional volumes need to be attached:
+
+* docker socket (/var/run/docker.sock)
+* conf dir (/etc/alpine-runner)
+* home dir (/home/gitlab-runner)
+
+For example:
+
+```sh
+docker run -d \
+    -v /srv/gitlab-runner/conf:/etc/gitlab-runner \
+    -v /srv/gitlab-runner/home:/home/gitlab-runner \
+    -v /var/run/docker.sock:/var/run/docker.sock \
+    gitlab-runner
+```
+
+You can execute `./run` to run this command
+
+## Register the runner
+
+There is a `./register-runner` command available in the container to register it.
+
+To execute it, use the following command:
+
+```sh
+docker exec -e ARCH=<arch> -e GITLAB_REGISTER_TOKEN=<token> <container> register-runner
+```
+
+* `ARCH` is added as a tag on the runner
+* `GITLAB_REGISTER_TOKEN` is a token you can find under `Settings > CI / CD > Runners`
+  of a specific project or under `Admin > Overview > Runners`.
