# Ace API Reference

Welcome to the Ace API Reference Guide. Ace is a standalone code editor written in JavaScript that you can embed onto any website. We're used in a bunch of places already, like GitHub, Google, and Facebook.

On the left, you'll find a list of all of our currently documented classes. There are plenty more to do, but these represent the "core" set. For more information on how to work with Ace, check out the main Ace website.
