Unless something has changed in the repo, the Github description -- as close to a "headline" that a Github repo can get -- is: "the only cheat sheet you need"

I agree that "Meta cheatsheet" is not a very effective title. When the repo doesn't have a Github description, I usually go with:

      [repo name] - [first line of README.md]

In this case:

cheat.sh - Unified access to community-driven cheat sheets repo of the world.

(I modified it to abbreviate "repositories" to "repo" and to omitted the phrase "the best", to go along with HN's rule for avoiding sensationalism.)
