7CodeMirror is a versatile text editor implemented in JavaScript for
8the browser. It is specialized for editing code, and comes with over

10editing functionality. Every language comes with fully-featured code
11and syntax highlighting to help with reading and editing complex code.

13A rich programming API and a CSS theming system are available for
14customizing CodeMirror to fit your application, and extending it with

40distribution channel. Cloning it is not the recommended way to install
41the library, and will in fact not work unless you also run the build
42step.

44### Quickstart
