+## Clone the Repo
+
+Go to [csmctl at Github](https://github.com/SovereignCloudStack/csmctl/) and clone the repository to your local device:
+
+```shell
+git clone git@github.com:SovereignCloudStack/csmctl.git
+```
+
+```shell
+cd csmctl
+```
+
+## Makefile
+
+We use a `Makefile` to building the binary.
+
+You can see the available build targets with `make help`.
+
+## make build
+
+With `make build` you create the executable.
+
+## csmctl --help
+
+With `./csmctl --help` you can see the available sub-commands.
+
+BTW: Be sure to use `./`, so that you don't accidentally use a different `csmctl` from your `$PATH`.
+
+Up to now only `create` is a feasible sub-command.
+
+## go run main.go ...     
+
+If you modify the source of `csmctl`, you can skip the build step by using `go run`:
+
+```shell
+go run main.go create --help
+```
+
+## Create Docker Cluster Stack
+
+In the `tests` directory is a cluster stack for the docker provider.
+
+You can create the cluster stack like this:
+
+```shell
+❯ go run main.go create tests/cluster-stacks/docker/ferrol -m hash
