+3. **Isolate the demonstrable problem** — Try to reproduce the problem with the [Demo](https://blueimp.github.io/jQuery-File-Upload/) or with a reduced test case that includes the least amount of code necessary to reproduce the problem.
+
+4. **Provide a means to reproduce the problem** — Please provide as much details as possible, e.g. server information, browser and operating system versions, steps to reproduce the problem. If possible, provide a link to your reduced test case, e.g. via [JSFiddle](http://jsfiddle.net/). 
+
+
+## Feature requests
+
+Please follow the bug guidelines above for feature requests, i.e. update to the latest version and search for exising issues before posting a new request.
+
+Generally, feature requests might be accepted if the implementation would benefit a broader use case or the project could be considered incomplete without that feature.

You are welcome to add a link and possibly documentation about your implementation to the [Wiki](https://github.com/blueimp/jQuery-File-Upload/wiki).
+
+Please follow these guidelines before sending a pull request:
+
+1. Update your fork to the latest upstream version.
+
+2. Follow the coding conventions of the original repository. Changes to one of the JavaScript source files are required to pass the [JSHint](http://www.jshint.com/) validation tool.
+
+3. Keep your commits as atomar as possible, i.e. create a new commit for every single bug fix or feature added.
+
+4. Always add meaningfull commit messages.

+# jQuery File Upload Plugin
+
+## Demo
+[Demo File Upload](https://blueimp.github.io/jQuery-File-Upload/)
+
+## Description
+File Upload widget with multiple file selection, drag&drop support, progress bars, validation and preview images, audio and video for jQuery.  
+Supports cross-domain, chunked and resumable file uploads and client-side image resizing. Works with any server-side platform (PHP, Python, Ruby on Rails, Java, Node.js, Go etc.) that supports standard HTML form file uploads.
+
+## Setup
+* [How to setup the plugin on your website](https://github.com/blueimp/jQuery-File-Upload/wiki/Setup)
+* [How to use only the basic plugin (minimal setup guide).](https://github.com/blueimp/jQuery-File-Upload/wiki/Basic-plugin)
+
+## Support
+
+* **[Support Forum](https://groups.google.com/d/forum/jquery-fileupload)**  
+**Support requests** and **general discussions** about the File Upload plugin can be posted to the official
+[Support Forum](https://groups.google.com/d/forum/jquery-fileupload).  
+If your question is not directly related to the File Upload plugin, you might have a better chance to get a reply by posting to [Stack Overflow](http://stackoverflow.com/questions/tagged/blueimp+jquery+file-upload).
+
+* Bugs and Feature requests  
+**Bugs** and **Feature requests** can be reported using the [issues tracker](https://github.com/blueimp/jQuery-File-Upload/issues).  
+Please read the [issue guidelines](https://github.com/blueimp/jQuery-File-Upload/blob/master/CONTRIBUTING.md) before posting.
+
+## Features
+* **Multiple file upload:**  
+  Allows to select multiple files at once and upload them simultaneously.
+* **Drag & Drop support:**  
+  Allows to upload files by dragging them from your desktop or filemanager and dropping them on your browser window.
+* **Upload progress bar:**  
+  Shows a progress bar indicating the upload progress for individual files and for all uploads combined.
+* **Cancelable uploads:**  
+  Individual file uploads can be canceled to stop the upload progress.
+* **Resumable uploads:**  
+  Aborted uploads can be resumed with browsers supporting the Blob API.
+* **Chunked uploads:**  
+  Large files can be uploaded in smaller chunks with browsers supporting the Blob API.
+* **Client-side image resizing:**  
+  Images can be automatically resized on client-side with browsers supporting the required JS APIs.
+* **Preview images, audio and video:**  
+  A preview of image, audio and video files can be displayed before uploading with browsers supporting the required APIs.
+* **No browser plugins (e.g. Adobe Flash) required:**  
+  The implementation is based on open standards like HTML5 and JavaScript and requires no additional browser plugins.
+* **Graceful fallback for legacy browsers:**  
+  Uploads files via XMLHttpRequests if supported and uses iframes as fallback for legacy browsers.
+* **HTML file upload form fallback:**  
+  Allows progressive enhancement by using a standard HTML file upload form as widget element.
+* **Cross-site file uploads:**  
+  Supports uploading files to a different domain with cross-site XMLHttpRequests or iframe redirects.
+* **Multiple plugin instances:**  
+  Allows to use multiple plugin instances on the same webpage.
+* **Customizable and extensible:**  
+  Provides an API to set individual options and define callBack methods for various upload events.
+* **Multipart and file contents stream uploads:**  
+  Files can be uploaded as standard "multipart/form-data" or file contents stream (HTTP PUT file upload).
+* **Compatible with any server-side application platform:**  
+  Works with any server-side platform (PHP, Python, Ruby on Rails, Java, Node.js, Go etc.) that supports standard HTML form file uploads.
+
+## Requirements
+
+### Mandatory requirements
+* [jQuery](https://jquery.com/) v. 1.6+
+* [jQuery UI widget factory](https://api.jqueryui.com/jQuery.widget/) v. 1.9+ (included)
+* [jQuery Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) (included)
+
+The jQuery UI widget factory is a requirement for the basic File Upload plugin, but very lightweight without any other dependencies from the jQuery UI suite.
+
+The jQuery Iframe Transport is required for [browsers without XHR file upload support](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support).
+
+### Optional requirements
+* [JavaScript Templates engine](https://github.com/blueimp/JavaScript-Templates) v. 2.5.4+
+* [JavaScript Load Image library](https://github.com/blueimp/JavaScript-Load-Image) v. 1.13.0+
+* [JavaScript Canvas to Blob polyfill](https://github.com/blueimp/JavaScript-Canvas-to-Blob) v. 2.1.1+
+* [blueimp Gallery](https://github.com/blueimp/Gallery) v. 2.15.1+
+* [Bootstrap CSS framework](http://getbootstrap.com/) v. 3.2.0+
+* [Glyphicons](http://glyphicons.com/)
+
+The JavaScript Templates engine is used to render the selected and uploaded files for the Basic Plus UI and jQuery UI versions.
+
+The JavaScript Load Image library and JavaScript Canvas to Blob polyfill are required for the image previews and resizing functionality.
+
+The blueimp Gallery is used to display the uploaded images in a lightbox.
+
+The user interface of all versions except the jQuery UI version is built with Twitter's [Bootstrap](http://getbootstrap.com/) framework 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.
+
+## Browsers
+
+### Desktop browsers
+The File Upload plugin is regularly tested with the latest browser versions and supports the following minimal versions:
+
+* Google Chrome
+* Apple Safari 4.0+
+* Mozilla Firefox 3.0+
+* Opera 11.0+
+* Microsoft Internet Explorer 6.0+
+
+### Mobile browsers
+The File Upload plugin has been tested with and supports the following mobile browsers:
+
+* Apple Safari on iOS 6.0+
+* Google Chrome on iOS 6.0+
+* Google Chrome on Android 4.0+
+* Default Browser on Android 2.3+
+* Opera Mobile 12.0+
+
+### Supported features
+For a detailed overview of the features supported by each browser version please have a look at the [Extended browser support information](https://github.com/blueimp/jQuery-File-Upload/wiki/Browser-support).
