This document provides information about using the Hedwig Slack bot plugin for Elixir. It discusses self-promotion, getting started by following the Hedwig_slack README, generating a robot worker, configuring tokens, and using responders and macros to handle messages. Suggestions are given such as using "respond" style responders instead of "hear" to avoid loops, keeping app logic separate from responders, and getting separate dev and prod tokens to avoid rate limits.
