+Dropzone.js is a light weight JavaScript library that turns an HTML element into a dropzone.
+This means that a user can drag and drop a file onto it, and the file gets uploaded to the server via AJAX.

+Starting with version 2.0.0 this library does no longer depend on jQuery (but
+it still works as a jQuery module).
+
+Dropzone is compatible with [component](https://github.com/component/component),
+there's a standalone version and an [AMD](https://github.com/amdjs/amdjs-api/wiki/AMD)
+module that's compatible with [RequireJS](http://requirejs.org) in the downloads
+folder.

+## Main features
+
+- Image thumbnail previews. Simply register the callback `thumbnail(file, data)` and display the image wherever you like
+- Retina enabled
+- Multiple files and synchronous uploads
+- Progress updates
+- Support for large files
+- Complete theming. The look and feel of Dropzone is just the default theme. You
+  can define everything yourself by overwriting the default event listeners.
+- Well tested
+
+## Documentation
+
+For the full documentation and installation please visit www.dropzonejs.com
+
+Please also refer to the [FAQ](https://github.com/enyo/dropzone/wiki/FAQ).
+
+## Examples
+
+For examples, please see the [GitHub wiki](https://github.com/enyo/dropzone/wiki).
+
+## Usage
+
+Implicit creation:
+
+```html
+<form id="my-awesome-dropzone" action="/target" class="dropzone"></form>
+```
+
+That's it. Really!
+
+Dropzone will automatically attach to it, and handle file drops.
+
+Want more control? You can configure dropzones like this:
+
+```js
+// "myAwesomeDropzone" is the camelized version of the ID of your HTML element
+Dropzone.options.myAwesomeDropzone = { maxFilesize: 1 };
+```
+
+...or instantiate dropzone manually like this:
+
+```js
+new Dropzone("div#my-dropzone", { /* options */ });
+```
+
+> Note that dropzones don't have to be forms. But if you choose another element you have to pass the `url` parameter in the options.
+
+For configuration options please look at the [documentation on the website](http://www.dropzonejs.com/#configuration)
+or at the [source](https://github.com/enyo/dropzone/blob/master/src/dropzone.coffee#L90).
+
+
+
+### Register for events
+
+If you want to register to some event you can do so on the `dropzone` object itself:
+
+```js
+Dropzone.options.myDropzone({
+  init: function() {
+    this.on("error", function(file, message) { alert(message); });
+  }
+});
+// or if you need to access a Dropzone somewhere else:
+var myDropzone = Dropzone.forElement("div#my-dropzone");
+myDropzone.on("error", function(file, message) { alert(message); });
+```
+
+For a list of all events, please look at the chapter 
+[»listen to events«](http://www.dropzonejs.com/#listen_to_events) in the documentation
+or at the [source](src/dropzone.coffee#L43).
+
+
+## Browser support
+
+- Chrome 7+
+- Firefox 4+
+- IE 10+
+- Opera 12+ (Version 12 for MacOS is disabled because their API is buggy)
+- Safari 6+
+
+For all the other browsers, dropzone provides an oldschool file input fallback.
+
+## Why another library?
+
+I realize that there [are](http://valums.com/ajax-upload/) [already](http://tutorialzine.com/2011/09/html5-file-upload-jquery-php/) [other](http://code.google.com/p/html5uploader/) [libraries](http://blueimp.github.com/jQuery-File-Upload/) out there but the reason I decided to write my own are the following:
+
+- I didn't want it to be too big, and to cumbersome to dive into.
+- I want to design my own elements. I only want to register callbacks so I can update my elements accordingly.
+- Big files should get uploaded without a problem.
+- I wanted a callback for image previews, that don't kill the browser if too many too big images are viewed.
+- I want to use the latest API of browsers. I don't care if it falls back to the normal upload form if the browser is too old.
+- I don't think that it's necessary anymore to depend on libraries such as jQuery (especially when providing functionality that isn't available in old browsers anyway).
