Building and Testing Pure
-------------------------

Pure uses [Grunt][], a JavaScript task runner that runs on [Node.js][], for
building and testing. You'll need Node.js and Grunt installed to work on Pure.
Once installed, clone the `pure` repo (either the main repo or your fork) and
install Pure's gruntplugins via npm:

```shell
$ git clone git://github.com/yui/pure.git
$ cd pure/
$ npm install
```

Building Pure is easy, run `grunt`:

```shell
$ grunt
```

Pure uses [CSSLint][] for basic testing to make sure we're shipping valid CSS
which complies with standard best practices. To run Pure's tests, run
`grunt test`:

```shell
$ grunt test
```

**Note:** To save your fingers from The Developer Konami Code: ⌘⇥ ↑ ⏎ run the
`grunt watch` task with will continuously test and build Pure anytime a CSS file
changes:

```shell
$ grunt watch
```

### Browser Support and Testing

Pure is tested and works in:

* IE 7+
* Latest Stable: Firefox, Chrome, Safari
* iOS 6.x
* Android 4.x

Before sending pull requests, please ensure that you open the test HTML files
in these environments. If you don't have access to all these environments, list
the ones that you have tested in on the pull request description. That way, we
know what's missing, and can help you out.
