-This package includes everything you'll need to use Video.js on a production site. By default, we bundle Video.js with Mozilla's excellent [VTT.js](https://github.com/mozilla/vtt.js). If you don't need VTT.js functionality for whatever reason, you can use one of the Video.js copies that don't include VTT.js. These have <code>novtt</code> in the name and can be found in the <code>alt/</code> directory. <code>font/</code> includes all the generated icon font files from the [Videojs Font project](https://github.com/videojs/font). <code>lang/</code> contains all the generated translation files.
