##Getting Started
Although the most straightforward way to use Torque is through either the CartoDB editor, or by passing the layer's viz.json to [CartoDB.js](http://docs.cartodb.com/cartodb-platform/cartodb-js/getting-started/), many use cases work best with the standalone [Torque.js](https://github.com/CartoDB/torque/tree/master/dist). Assuming you have a public dataset with a `date` column, it's really simple to create an animated map with the library. First you need to have a Leaflet map prepared in an HTML page:

Like in a video player, you can use animation control methods such as `play`, `stop` and `pause` at any point. Torque's animator fires a `change:time` event each time the animation "ticks" to the next frame, and there are a number of properties and methods that can be run during playback, which are detailed in the [API documentation](../torque_api.md). At any point, for example, the styling of the layer's markers can be changed using the `layer.setCartoCSS('##style##')`.

##Usage examples
##Usage Examples
The best way to start learning about the library is by taking a look at some of the examples below:
