 You can easily install whipper by making use of the included Dockerfile without needing to care about the required dependencies:
 
-`docker build -t whipper/whipper:0.7-git -t whipper/whipper:latest`
+`docker build -t whipper/whipper`
 
 It's recommended to create an alias for a convenient usage:
 
 ```bash
 alias whipper="docker run -ti --rm --device=/dev/cdrom \
-    -v ${PWD}/config:/home/worker/.config/whipper \
+    -v ~/.config/whipper:/home/worker/.config/whipper \
     -v ${PWD}/output:/output \
     whipper/whipper"
 ```
