| |
| CodeMirror is a versatile text editor implemented in JavaScript for |
| the browser. It is specialized for editing code, and comes with over |
| 100 language modes and various addons that implement more advanced |
| editing functionality. |
| |
| A rich programming API and a CSS theming system are available for |
| customizing CodeMirror to fit your application, and extending it with |
| new functionality. |

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