Quick instructions:
- run `gen-key.sh` to generate an ssh host key
- copy `.env.template` to `.env`
- set the server name  in `.env` to your fully-qualified domain name
- register a knot on tangled.sh and put the secret key in `.env`
- spin up the container and test that it works

The default service runs the ssh daemon on port 2222, so I use something
like this in my `~/.ssh/config` to make it more seamless.

```
Host git.recoil.org
  User git
  Port 2222
```

Buyer beware, this is a very new and untested setup for alpha software,
so don't commit any overly precious code to this.
