8CodeMirror is a versatile text editor implemented in JavaScript for
9the browser. It is specialized for editing code, and comes with over
10100 language modes and various addons that implement more advanced
11editing functionality. Every language comes with fully-featured code
12and syntax highlighting to help with reading and editing complex code.

14A rich programming API and a CSS theming system are available for
15customizing CodeMirror to fit your application, and extending it with
16new functionality.

40**NOTE**: This is the source repository for the library, and not the
41distribution channel. Cloning it is not the recommended way to install
42the library, and will in fact not work unless you also run the build
43step.

45### Quickstart
46
47To build the project, make sure you have Node.js installed (at least version 6)
48and then `npm install`. To run, just open `index.html` in your
49browser (you don't need to run a webserver). Run the tests with `npm test`.
