 ## Requirements
-* [jQuery](http://jquery.com/) v. 1.6+
-* [jQuery UI widget factory](http://api.jqueryui.com/jQuery.widget/) v. 1.9+ (included)
-* [jQuery Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/jquery.iframe-transport.js) (included)
-* [JavaScript Templates engine](https://github.com/blueimp/JavaScript-Templates) v. 2.1.0+ (optional)
-* [JavaScript Load Image function](https://github.com/blueimp/JavaScript-Load-Image) v. 1.2.1+ (optional)
-* [JavaScript Canvas to Blob function](https://github.com/blueimp/JavaScript-Canvas-to-Blob) v. 2.0.3+ (optional)
-* [Bootstrap CSS Toolkit](https://github.com/twitter/bootstrap/) v. 2.1+ (optional)
 
-The jQuery UI widget factory is a requirement for the basic File Upload plugin, but very lightweight without any other dependencies.  
-The jQuery Iframe Transport is required for [browsers without XHR file upload support](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support).  
-The UI version of the File Upload plugin also requires the JavaScript Templates engine as well as the JavaScript Load Image and JavaScript Canvas to Blob functions (for the image previews and resizing functionality). These dependencies are marked as optional, as the basic File Upload plugin can be used without them and the UI version of the plugin can be extended to override these dependencies with alternative solutions.
+### Mandatory requirements
+* [jQuery](https://jquery.com/) v. 1.6+
+* [jQuery UI widget factory](https://api.jqueryui.com/jQuery.widget/) v. 1.9+ (included): Required for the basic File Upload plugin, but very lightweight without any other dependencies from the jQuery UI suite.
+* [jQuery Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) (included): Required for [browsers without XHR file upload support](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support).
 
-The User Interface is built with Twitter's [Bootstrap](https://github.com/twitter/bootstrap/) Toolkit. This enables a CSS based, responsive layout and fancy transition effects on modern browsers. The demo also includes the [Bootstrap Image Gallery Plugin](https://github.com/blueimp/Bootstrap-Image-Gallery). Both of these components are optional and not required.
+### Optional requirements
+* [JavaScript Templates engine](https://github.com/blueimp/JavaScript-Templates) v. 2.5.4+: Used to render the selected and uploaded files for the Basic Plus UI and jQuery UI versions.
+* [JavaScript Load Image library](https://github.com/blueimp/JavaScript-Load-Image) v. 1.13.0+: Required for the image previews and resizing functionality.
+* [JavaScript Canvas to Blob polyfill](https://github.com/blueimp/JavaScript-Canvas-to-Blob) v. 2.1.1+:Required for the image previews and resizing functionality.
+* [blueimp Gallery](https://github.com/blueimp/Gallery) v. 2.15.1+: Used to display the uploaded images in a lightbox.
+* [Bootstrap](http://getbootstrap.com/) v. 3.2.0+
+* [Glyphicons](http://glyphicons.com/)
 
-The repository also includes the [jQuery XDomainRequest Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/cors/jquery.xdr-transport.js), which enables Cross-domain AJAX requests (GET and POST only) in Microsoft Internet Explorer >= 8. However, the XDomainRequest object doesn't support file uploads and the plugin is only used by the [Demo](http://blueimp.github.com/jQuery-File-Upload/) for Cross-domain requests to delete uploaded files from the demo file upload service.
+The user interface of all versions, except the jQuery UI version, is built with [Bootstrap](http://getbootstrap.com/) and icons from [Glyphicons](http://glyphicons.com/).
 
+### Cross-domain requirements
 [Cross-domain File Uploads](https://github.com/blueimp/jQuery-File-Upload/wiki/Cross-domain-uploads) using the [Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) require a redirect back to the origin server to retrieve the upload results. The [example implementation](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/main.js) makes use of [result.html](https://github.com/blueimp/jQuery-File-Upload/blob/master/cors/result.html) as a static redirect page for the origin server.
 
+The repository also includes the [jQuery XDomainRequest Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/cors/jquery.xdr-transport.js), which enables limited cross-domain AJAX requests in Microsoft Internet Explorer 8 and 9 (IE 10 supports cross-domain XHR requests).  
+The XDomainRequest object allows GET and POST requests only and doesn't support file uploads. It is used on the [Demo](https://blueimp.github.io/jQuery-File-Upload/) to delete uploaded files from the cross-domain demo file upload service.
+
+### Custom Backends
