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 Example — ExDoc v0.40.3
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.

We would absolutely love a PR that adds a print.css to ExDoc and makes the cheatsheets printable.

I would love to be able to print devhints cheatsheets out in paper, and wished they would provide printer friendly PDFs.

I saw you fork devhints on GitHub. I didn’t know you had such great plans.
Thanks for this awesome feature, now I can use hints without reservations.
