+# gif.js
+
+JavaScript GIF encoder that runs in your browser.
+
+Uses typed arrays and web workers to render each frame in the background, it's really fast!
+
+**Demo** - http://jnordberg.github.io/gif.js/
+
+Works in browsers supporting: [Web Workers](http://www.w3.org/TR/workers/), [File API](http://www.w3.org/TR/FileAPI/) and [Typed Arrays](https://www.khronos.org/registry/typedarray/specs/latest/)
+
+
+## Usage
+
+Include `gif.js` found in `dist/` in your page. Also make sure to have `gif.worker.js` in the same location.
+
+```javascript
+var gif = new GIF({
+  workers: 2,
+  quality: 10
+});
+
+// add an image element
+gif.addFrame(imageElement);
+
+// or a canvas element
+gif.addFrame(canvasElement, {delay: 200});
+
+// or copy the pixels from a canvas context
+gif.addFrame(ctx, {copy: true});
+
+gif.on('finished', function(blob) {
+  window.open(URL.createObjectURL(blob));
+});
+
+gif.render();
+
+```
+
+## Options
+
+Options can be passed to the constructor or using the `setOptions` method.
+
+| Name         | Default         | Description                                        |
+| -------------|-----------------|----------------------------------------------------|
+| repeat       | `0`             | repeat count, `-1` = no repeat, `0` = forever      |
+| quality      | `10`            | pixel sample interval, lower is better             |
+| workers      | `2`             | number of web workers to spawn                     |
+| workerScript | `gif.worker.js` | url to load worker script from                     |
+| background   | `#fff`          | background color where source image is transparent |
+| width        | `null`          | output image width                                 |
+| height       | `null`          | output image height                                |
+| transparent  | `null`          | transparent hex color, `0x00FF00` = green          |
+| dither       | `false`         | dithering method, e.g. `FloydSteinberg-serpentine` |
+| debug        | `false`         | whether to print debug information to console      |
+
+If width or height is `null` image size will be deteremined by first frame added.
+
+Available dithering methods are:
+
+ * `FloydSteinberg`
+ * `FalseFloydSteinberg`
+ * `Stucki`
+ * `Atkinson`
+
+You can add `-serpentine` to use serpentine scanning, e.g. `Stucki-serpentine`.
