+[![Codecov](https://img.shields.io/codecov/c/github/muxinc/media-tracks?style=flat-square)](https://app.codecov.io/gh/muxinc/media-tracks)
+
+
+Polyfills the media elements (`<audio>` or `<video>`) adding audio and video tracks (as [specced](https://html.spec.whatwg.org/multipage/media.html#media-resources-with-multiple-media-tracks)) and with renditions as proposed in [media-ui-extensions](https://github.com/video-dev/media-ui-extensions).
+
+- Allows media engines like [hls.js](https://github.com/video-dev/hls.js)
+or [shaka](https://github.com/shaka-project/shaka-player) to add media tracks w/
+renditions from the information they retrieve from the manifest to a standardized
+API.
+- Allows media UI implementations like [media-chrome](https://github.com/muxinc/media-chrome) to consume this uniform API and render media track selection menus
+and rendition (quality) selection menus.
+
+
+## Caveats
+
+- iOS does not support manual rendition switching as it is using a native
+  HLS implementation. This library can't change anything about that.
