+# Dynamics.js
+Dynamics.js is a Javascript library to create physics-related CSS animations
+
+To see some demos, check out [dynamicsjs.com](http://dynamicsjs.com).
+
+## Usage
+Include `dynamics.js` into your page: [download here](https://github.com/michaelvillar/dynamics.js/releases)
+```
+<script src="dynamics.js"></script>
+```
+Example:
+```
+var el = document.getElementById("logo")
+dynamics.animate(el).to({
+  translateX: 350,
+  scale: 2,
+  opacity: 0.5
+}, {
+  type: dynamic.Spring,
+  frequency: 200,
+  friction: 200,
+  duration: 1000
+})
+```
+
+## Reference
+### dynamics.animate(el, properties, options)
+Animates an element to the properties with the animation options.
+- `el` is a DOM element or any Javascript object
+- `properties` is an object of the properties/values you want to animate
+- `options` is an object representing the animation
+  - `type` is the [animation type](#dynamics-and-properties): `dynamics.spring`, `dynamics.easeInOut`,... (default: `dynamics.easeInOut`)
+  - `frequency`, `friction`, `bounciness`,... are specific to the animation type you are using
+  - `duration` is in milliseconds (default: `1000`)
+  - `complete` (optional) is the completion callback
+  - `change` (optional) is called at every change
+
+### dynamics.stop(el)
+Stops the animation applied on the element
+
+### dynamics.css(el, properties)
+This is applying the CSS properties to your element with the correct browser prefixes.
+- `el` is a DOM element
+- `properties` is an object of the CSS properties
+
+### dynamics.setTimeout(fn, delay)
+Dynamics.js has its own `setTimeout`. The reason is that `requestAnimationFrame` and `setTimeout` have different behaviors. In most browsers, `requestAnimationFrame` will not run in a background tab while `setTimeout` will. This can cause a lot of problems while using `setTimeout` along your animations. I suggest you use Dynamics's `setTimeout` and `clearTimeout` to handle these scenarios.
+- `fn` is the callback
+- `delay` is in milliseconds
+Returns a unique id
+
+### dynamics.clearTimeout(id)
+Clears a timeout that was defined earlier
+- `id` is the timeout id
+
+## Dynamics and properties
+### dynamics.spring
+- `frequency`: default is 300
+- `friction`: default is 200
+- `anticipationSize` (optional)
+- `anticipationStrength` (optional)
+
+### dynamics.bounce
+- `frequency`: default is 300
+- `friction`: default is 200
+
+### dynamics.forceWithGravity and dynamics.gravity
+- `bounciness`: default is 400
+- `elasticity`: default is 200
+
+### dynamics.easeInOut, dynamics.easeIn and dynamics.easeOut
+- `friction`: default is 500
+
+### dynamics.linear
+No properties
+
+### dynamics.bezier
+- `points`: array of points and control points
+
+The easiest way to output this kind of array is to use the [curve creator](http://dynamicsjs.com). Here is an example:
+```
+[{"x":0,"y":0,"cp":[{"x":0.2,"y":0}]},
+ {"x":0.5,"y":-0.4,"cp":[{"x":0.4,"y":-0.4},{"x":0.8,"y":-0.4}]},
+ {"x":1,"y":1,"cp":[{"x":0.8,"y":1}]}]
+```
