Better install instructions

[noraj]

It is possible to provide a more detailed install guide (in README or docs/wiki).

As this one I wrote on another project https://github.com/mitre-cyber-academy/ctf-scoreboard/blob/d59eced1dbf6830015c35687667afb89a54eba7e/README.md

I'll maybe PR when I'll have time.

I do all my deployments on Swarm now. I've been working on making sure the docker images I push to (paullj1/hackthearch) are in line with releases here. Deployment when using swarm is SUPER straightforward. You can even use the yml file that's checked in to the repo.
