## Installation

### GNU/Linux (with [Nix](https://nixos.org/nix/))

    $ curl -fsSL https://get.docker.com | sh
	$ sudo usermod -aG docker user && newgrp docker
    $ curl -L https://nixos.org/nix/install | sh
    $ nix-env -iA nixpkgs.out-of-tree # Note: may not be up to date immediately, in this case consider installing from source

Note that adding a user to group *docker* has serious security implications. Check Docker documentation for more information.

    $ brew install podman
    $ podman machine stop || true
    $ podman machine rm || true
    $ podman machine init --cpus=4 --memory=4096 -v $HOME:$HOME
