 ## Setup / Usage
 
 How to setup docker and start the cluster image.
 
-- Install `docker` on your system. 1.0 or higher is recommended. Instructions can be found at http://docs.docker.com/en/latest/installation/. It is also reccomended to add the current user to `docker` system group to remove the need to add sudo to each docker call.
-- Run `make docker-build` or `make docker-rebuild` to build the image. When rebuilding the image, no cached layers will be used.
-- Run one of
-
-  - `make docker-run` to start the server and tail first redis server (the one creating the cluster)
-  - `make docker-run-d` to run it in the background.
-  - `make docker-run-interactive` starts `/bin/bash` (good for debugging) [`start.sh` have to be runned manually. No cluster will be created, Supervisord will not start automatically]

+
+To build the image run either `make dbuild` or `make drebuild`. It will be built to the image name `grokzen/redis-cluster`.
+
+To start the image run `make drun`. It will be started in the background. To gain access to the running image you can get a bash session by running `make dbash`.
 
-- Test to connect to the cluster with `redis-cli -p 7000`. If you do not want to install a redis server on your host to get access to `redis-cli` you can run a `exec` command to run it inside the docker container. It can be done with `docker exec -it <ContainerID> /redis/src/redis-cli -p 7000` where `<ContainerID>` can be found via `docker ps`
