# CheSSH
2023-02-24 17:59:42 -05:00
CheSSH is a distributed multiplayer implementation of the game of Chess over SSH,
written in Elixir, with Discord integrations to deliver alerts when players are
2023-02-25 01:37:52 -05:00
looking for opponents, or in games when it is one's turn.

## Bots
As a user, you can create 2 bot accounts at [/bots](https://chessh.linux.usu.edu/bots). These are driven by
webhooks.
For an example bot, see [chessh example bot](https://github.com/Simponic/chessh_bot).

## Architecture
The process of building the pi cluster is wholly contained in the awful
`buildscripts`, which will individually `ssh` into separate pi's and build the
services locally there as well as update the load balancer pi's configurations for nginx
and HAproxy.
More architecture talk of CheSSH can be found in my (albeit kinda cringe) FSLC
presentation on Elixir:
