-npm # Video thumbnails + WebVTT using Node.js
-
-Thumbnails generator module. Uses [WebVTT](http://dev.w3.org/html5/webvtt/) as thumbnails descriptor. Can pack thumbnails into spritesheet using [node-sprit]() module.
-
-## Installation
-
-    npm install thumbnails-webvtt --save
-
-## Requirements
-
-* [ffmpeg](https://www.ffmpeg.org/) used by `fluent-ffmpeg` 
-* [ImageMagick](http://www.imagemagick.org/) as used by `node-sprite`
-
-## Example
-
-```javascript
-'use strict'
-
-var thumbgen = require('thumbnails-webvtt')
-
-thumbgen('/media/Hammer.of.the.Gods.2013.BluRay.720p.mkv', {
-  output:          '/vtt/Hammer.of.the.Gods.2013.BluRay.720p.vtt',
-  size:            {
-    width: 480
-  },
-  numThumbnails:   6,
-  spritesheet:     true
-}, function(err, metadata) {
-  if (err) {
-    throw err
-  }
-  
-  console.dir(metadata)
-})
-```
-
-will print
