# CodeMirror 5

**NOTE:** [CodeMirror 6](https://codemirror.net/) exists, and is more mobile-friendly, more accessible, better designed, and much more actively maintained.

[![Build Status](https://github.com/codemirror/codemirror5/workflows/main/badge.svg)](https://github.com/codemirror/codemirror5/actions)

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. Every language comes with fully-featured code

and syntax highlighting to help with reading and editing complex code.

A rich programming API and a CSS theming system are available for

customizing CodeMirror to fit your application, and extending it with

new functionality.

You can find more information (and the

[manual](https://codemirror.net/5/doc/manual.html)) on the [project

page](https://codemirror.net/5/). For questions and discussion, use the

[discussion forum](https://discuss.codemirror.net/).

### Installation

Either get the [zip file](https://codemirror.net/5/codemirror.zip) with

the latest version, or make sure you have [Node](https://nodejs.org/)

installed and run:

    npm install codemirror@5

**NOTE**: This is the source repository for the library, and not the

distribution channel. Cloning it is not the recommended way to install

the library, and will in fact not work unless you also run the build

step.

### Quickstart

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`.
