## Getting Started

You have a few options for getting the icon set.

### Download the Zip

### Bower

```sh
$ bower install material-design-icons
```

### npm

You can also find all the icons on [npm](http://npmjs.org).

## Structure

### Icons

### Spritesheets

Material Design icons come with SVG and CSS sprites for each category of icon we include. These can be found in the `sprites` directory, under the `svg-sprite` and `css-sprite` sub-directories.

#### Using CSS Sprites

To use a CSS spritesheet, reference the stylesheet for the icon category you wish to use, then include the icon definition in your markup. 

E.g: to use one of the play icons in `css-sprite-av`, we would do the following:

Reference the stylesheet:

```html
	<link href="css-sprite/sprite-av-black.css" rel="stylesheet">
```

Create an element which will use the icon as a background:

```html
	<div></div>
```

Add a class referencing the `icon` spritesheet and specific icon `icon-ic_play_circle_outline_black_24dp`, which you can get from the above stylesheet.

```html
	<div class="icon icon-ic_play_circle_outline_black_24dp"></div>
```

That's it!

Don't forget to publish the corresponding CSS and SVG/PNG files when deploying your project.
