This is what I came up with: if you want to read the cheat sheet for React, just type
$ hint react
and, voila, the sheet appears.

mdless, which you can install using your favorite package manager. The sheets are fetched from Devhints.IO’s Github repository.
Sheet files are cached in
$HOME/.hack and can be refreshed using the
--refresh command line argument.
If you like the idea of cheat sheets in your terminal, you might also want to checkout TLDR, which explains tools using examples - basically it just reverses the classic man pages ;)
Let me know if you have a better way or some idea for improving this tiny snippet:
