Unified access to the best community driven cheat sheets repositories of the world.

Let's imagine for a moment that there is such a thing as an ideal cheat sheet.
What should it look like?
What features should it have?

* **Concise** — It should only contain the things you need, and nothing else.
* **Fast** — It should be possible to use it instantly.
* **Comprehensive** — It should contain answers for every possible question.
* **Universal** — It should be available everywhere, anytime, without any preparations.
* **Unobtrusive** — It should not distract you from your main task.
* **Tutoring** — It should help you to learn the subject.
* **Inconspicuous** — It should be possible to use it completely unnoticed.

Such a thing exists! It's easy to [install](#installation) and there's even [auto-complete](#tab-completion).


## Features

**cheat.sh**

* Has a simple curl/browser/editor interface.
* Covers 56 programming languages, several DBMSes, and more than 1000 most important UNIX/Linux commands.
* Provides access to the best community driven cheat sheets repositories in the world, on par with StackOverflow.
* Available everywhere, no installation needed, but can be installed for offline usage.
* Ultrafast, returns answers within 100 ms, as a rule.
* Has a convenient command line client, `cht.sh`, that is very advantageous and helpful, though not mandatory.
* Can be used directly from code editors, without opening a browser and not switching your mental context.
* Supports a special stealth mode where it can be used fully invisibly without ever touching a key and making sounds.
