## Developing Node Modules

Atom contains a number of packages that are Node modules instead of Atom packages. If you want to
make changes to the Node modules, for instance `atom-keymap`, you have to link them into the
development environment differently than you would a normal Atom package.

### Linking a Node Module Into Your Atom Dev Environment

Here are the steps to run a local version of a node module *not an apm* within Atom. We're using
`atom-keymap` as an example:

```bash
$ git clone https://github.com/atom/atom-keymap.git
$ cd atom-keymap
$ npm install
$ npm link
$ apm rebuild # This is the special step, it makes the npm work with Atom's version of Node
$ cd WHERE-YOU-CLONED-ATOM
$ npm link atom-keymap
$ atom # Should work!
```

After this, you'll have to `npm install` and `apm rebuild` when you make a change to the node
module's code.
