## Documentation
Our documentation site lives at [primer.style/css](https://primer.style/css). You'll be able to find detailed documentation on getting started, all of the components, our theme, our principles, and more.

## Install
This repository is distributed with [npm]. After [installing npm][install-npm], you can install `@primer/css` with this command:

```sh
npm install --save @primer/css
```

## Usage
The included source files are written in [Sass] using SCSS syntax. Once installed, you can add your project's `node_modules` directory to your Sass [include paths](https://github.com/sass/node-sass#includepaths) (AKA [load paths](http://technology.customink.com/blog/2014/10/09/understanding-and-using-sass-load-paths/) in Ruby), then import it like this:

```scss
@import "@primer/css/index.scss";
```

You can import individual Primer modules directly from the `@primer/css` package:

```scss
@import "@primer/css/core/index.scss";
@import "@primer/css/product/index.scss";
@import "@primer/css/marketing/index.scss";
```

## Development
See [DEVELOP.md](DEVELOP.md) for development docs.

## Releasing (for GitHub staff)
You can find docs about our release process in [RELEASING.md](RELEASING.md).
