+
+Uppy plugin that generates small previews of images to show on your upload UI.
+
+Uppy is being developed by the folks at [Transloadit](https://transloadit.com), a versatile file encoding service.
+
+## Example
+
+```js
+const Uppy = require('@uppy/core')
+const ThumbnailGenerator = require('@uppy/thumbnail-generator')
+
+const uppy = Uppy()
+uppy.use(ThumbnailGenerator, {
+  thumbnailWidth: 200
+})
+```
+
+## Installation
+
+```bash
+$ npm install @uppy/thumbnail-generator --save
+```
+
+We recommend installing from npm and then using a module bundler such as [Webpack](http://webpack.github.io/), [Browserify](http://browserify.org/) or [Rollup.js](http://rollupjs.org/).
+
+Alternatively, you can also use this plugin in a pre-built bundle from Transloadit's CDN: Edgly. In that case `Uppy` will attach itself to the global `window.Uppy` object. See the [main Uppy documentation](https://uppy.io/docs/#Installation) for instructions.
+
+<!-- Undocumented currently
+## Documentation
+
+Documentation for this plugin can be found on the [Uppy website](https://uppy.io/docs/DOC_PAGE_HERE).
