ExDoc v0.29 is out with a new amazing feature: cheatsheets!
Alongside guides and API reference, cheatsheets are another option for Elixir/Erlang devs to share their knowledge with the community. Check the cheatsheet’s cheatsheet to get started: Cheatsheet User Guide — ExDoc v0.29.0
Cheatsheets are Markdown files with the .cheatmd extension - so they fit right in with the community practices. The work is heavily inspired by https://devhints.io from Rico Sta. Cruz (he also designed the Plug/Phoenix error pages!) and was a contribution from Paulo Valim.
I am looking forward to the cheatsheets the community will come up with and we will have some for Elixir soon.
