## Installation
Install MRSK globally with `gem install mrsk`. Then, inside your app directory, run `mrsk init` (or `mrsk init --bundle` within Rails apps where you want a bin/mrsk binstub). Now edit the new file `config/deploy.yml`. It could look as simple as this:
If you have a Ruby environment available, you can install MRSK globally with:
```sh
gem install mrsk
```
...otherwise, you can run a dockerized version via an alias (add this to your ${SHELL}rc to simplify re-use):
```sh
alias mrsk='docker run --rm -it -v $HOME/.ssh:/root/.ssh -v /var/run/docker.sock:/var/run/docker.sock -v ${PWD}/:/workdir ghcr.io/mrsked/mrsk'

2. Install Docker on any server that might be missing it (using apt-get): root access is needed via ssh for this.
3. Log into the registry both locally and remotely
4. Build the image using the standard Dockerfile in the root of the application.
