-## Installation
-
-[Download the Sketch library](sketch://add-library?url=https%3A%2F%2Fstatic.nrk.no%2Fcore-icons%2Flatest%2Fcore-icons.rss) for sketching, [individual SVGs](https://static.nrk.no/core-icons/latest/index.html#icons) for Android, [PDFs](https://static.nrk.no/core-icons/latest/index.html#icons) for iOS. All icons follow [BEM naming conventions](http://getbem.com/) and are prefixed with `nrk-` to play nice with existing code.
-
-### Using NPM
-
-```bash
-npm install @nrk/core-icons
-```
-
-All icons are exposed individually as exported constants (enabling [tree shaking](https://medium.com/@netxm/what-is-tree-shaking-de7c6be5cadd)):
-
-```js
-import { nrkLogoNrk } from '@nrk/core-icons'      // Vanilla JS, String
-import { NrkLogoNrk } from '@nrk/core-icons/jsx'  // React, ReactElement
-
-<NrkLogoNrk />                                    // Example render a NRK logo with React
-<span style={{ color: 'red', fontSize: 20 }}>     // Style is inherited from parent element
-  <NrkLogoNrk />
-</span>
-```
-
-### Using static
