-## Build
+## About
 
-```bash
-git clone https://github.com/dbarton/docker-couchpotato.git
-cd docker-couchpotato
-docker build -t <tag> .
+This is a Docker image for [CouchPotato](https://couchpota.to/) - the awesome movie PVR for usenet and torrents.
+
+## Configuration
+
+### Volumes
+
+Mount the following volumes inside your container:
+
+* `<datadir path>:/datadir`
+* `<media path>:/media`
+
+### Configuration file
+
+By default the CouchPotato configuration is located on:
+
+```
+/datadir/config.ini
 ```
 
+If you want to change this, set the `CONFIG` environment variable.
+
+### CouchPotato Version
+
+By default the latest CouchPotato version will be used by pointing at the `master` tree of the [CouchPotato git repository](https://github.com/RuudBurger/CouchPotatoServer).
+If you want a different version you've set the `VERSION` environment variable to a valid git branch or tag.
+
+_Please note that CouchPotato will automatically be updated when you restart your container._
+
 ## Run
 
+### Run via docker CLI
+
 ```bash
 docker run --name couchpotato -v <datadir path>:/datadir -v <media path>:/media dbarton/couchpotato
