### Plugins
**Outdated, this will be rewritten to match the 4.0 plugin API**
Plugins should register themselves with reveal.js by calling `Reveal.registerPlugin( MyPlugin )`. Registered plugins _must_ expose a unique `id` property and can optionally expose an `init` function that reveal.js will call to initialize them.
When reveal.js is booted up via `initialize()`, it will go through all registered plugins and invoke their `init` methods. If the `init` method returns a Promise, reveal.js will wait for that promise to be fulfilled before finishing the startup sequence and firing the [ready](#ready-event) event. Here’s an example of a plugin that does some asynchronous work before reveal.js can proceed:

Note that reveal.js will *not* wait for init Promise fulfillment if the plugin is loaded as an [async dependency](#dependencies). If the plugin’s init method does _not_ return a Promise, the plugin is considered ready right away and will not hold up the reveal.js startup sequence.

### Manually Registering Plugins
TBD. Describe how plugins can be registered after reveal.js is already initialized.
### Retrieving Plugins
If you want to check if a specific plugin is registered you can use the `Reveal.hasPlugin` method and pass in a plugin ID, for example: `Reveal.hasPlugin( ’myPlugin’ )`. If you want to retrieve a plugin instance you can use `Reveal.getPlugin( ’myPlugin’ )`.
If you want to check if a specific plugin is registered you can use the `Reveal.hasPlugin` method and pass in a plugin ID, for example: `Reveal.hasPlugin( ’my-plugin’ )`. If you want to retrieve a plugin instance you can use `Reveal.getPlugin( ’my-plugin’ )`.
