+## Running as Docker container
+
+If you run redis in a Docker container, the recommended way is to run rebrow in it's own Docker container, too. The provided `Dockerfile` can be used to create the according image. The `Makefile` contains example commands to build the image and run a container from the image.
+
+When running the image, make sure to get your links right. For example, if your redis server is running in a container named `myredis`, start your rebrow container like this:
+
+```
+docker run --rm -ti -p 5001:5001 --link myredis:myredis rebrow
+```
+
+Then access rebrow via `http://<your-docker-ip>:5001/` and set the host name in the login screen to `myredis`.
