-# GitHub Octicons
-
-[](https://www.npmjs.org/package/octicons)
-[](https://travis-ci.org/primer/octicons)
-
-> Octicons are a scalable set of icons handcrafted with <3 by GitHub.
-
-## Install
-
-**NOTE:** The compiled files are located in `/build/`. This directory is located in the published npm package. Which means you can access it when you `npm install octicons`. You can also build this directory by following the [building octicons directions](#building-octicons). The files in the `/lib/` directory are the raw source files and are not compiled or optimized.
-
-#### NPM
-
-This repository is distributed with [npm][npm]. After [installing npm][install-npm], you can install `octicons` with this command.
-
-```
-$ npm install --save octicons
-```
-
-## Usage
-
-For all the usages, we recommend using the CSS located in `./build/octicons.css`. This is some simple CSS to normalize the icons and inherit colors.
-
-### Spritesheet
-
-With a [SVG sprite icon system](https://css-tricks.com/svg-sprites-use-better-icon-fonts/) you can include the sprite sheet located `./build/sprite.octicons.svg` after you [build the icons](#building-octicons) or from the npm package. There is a demo of how to use the spritesheet in the build directory also.
-
-### Node
-
-After installing `npm install octicons` you can access the icons like this.
-
-```js
-var octicons = require("octicons")
-octicons.alert
-// { keywords: [ 'warning', 'triangle', 'exclamation', 'point' ],
-// path: '',
-// height: '16',
-// width: '16',
-// symbol: 'alert',
-// options:
-// { version: '1.1',
-// width: '16',
-// height: '16',
-// viewBox: '0 0 16 16',
-// class: 'octicon octicon-alert',
-// 'aria-hidden': 'true' },
-// toSVG: [Function] }
-```
-
-There will be a key for every icon, with `keywords` and `svg`.
-
-#### `octicons.alert.symbol`
-
-Returns the string of the symbol name
-
-```js
-octicons.x.symbol
-// "x"
-```
-
-#### `octicons.person.path`
-
-Path returns the string representation of the path of the icon.
-
-```js
-octicons.x.path
-//
-```
-
-#### `octicons.issue.options`
-
-This is a json object of all the `options` that will be added to the output tag.
-
-```js
-octicons.x.options
-// { version: '1.1', width: '12', height: '16', viewBox: '0 0 12 16', class: 'octicon octicon-x', 'aria-hidden': 'true' }
-```
-
-#### `octicons.alert.width`
-
-Width is the icon's true width. Based on the svg view box width. _Note, this doesn't change if you scale it up with size options, it only is the natural width of the icon_
-
-#### `octicons.alert.height`
-
-Height is the icon's true height. Based on the svg view box height. _Note, this doesn't change if you scale it up with size options, it only is the natural height of the icon_
-
-#### `keywords`
-
-Returns an array of keywords for the icon. The data [comes from the octicons repository](https://github.com/primer/octicons/blob/master/lib/data.json). Consider contributing more aliases for the icons.
-
-```js
-octicons.x.keywords
-// ["remove", "close", "delete"]
-```
-
-#### `octicons.alert.toSVG()`
-
-Returns a string of the svg tag
-
-```js
-octicons.x.toSVG()
-//
-```
-
-The `.toSVG()` method accepts an optional `options` object. This is used to add CSS classnames, a11y options, and sizing.
-
-##### class
-
-Add more CSS classes to the `
