 ## Spacing scale
 The spacing scale is a **base-8** scale. We chose a base-8 scale because eight is a highly composable number (it can be divided and multiplied many times and result in whole numbers), yet allows spacing dense enough for GitHub's UI. The scale's exception is that it begins at 4px to allow smaller padding and margin for denser parts of the site, from there on it steps up consistently in equal values of `8px`.

-[The Product UI Kit](https://github.com/github/design/blob/master/resources/sketch/github-ui-kit.sketch) is a collection of our core GitHub UI styles and components suitable for building mockups. It also includes a starter page template with a site and repo header.

-Don't waste time manually updating the Octicons artboard when icons are added, removed, or changed. See the [Octicons Sketch plugin](https://github.com/github/design/tree/master/resources/sketch/octicons-plugin) directory for a way to automate those updates.
