I guess it's too early to quote the "RTFM", because the step-by-step tutorial is in another pull request that contributors need to raise against the main Nomad repository so that the website can show the steps.
Nevertheless, the "examples" directory has the agent configuration and the example Nomad job file you'll need to deploy onto the server. Let me know if that helps.
Eg I like Nomad and would love to deploy wasm stuff there, but tbh have no idea how to get from building to deploying something using this driver
