 - **_(Important)_** Removed the requirement for a wrapper div to setup Plyr and removed the dependency on the `plyr` classname as a JS hook. By default it will now look for `<video>`, `<audio>` and `[data-type]` elements. If you are just calling `setup()` with a `<div class="plyr">` you may want to give it a good test after upgrading. You can probably remove the wrapper div. The reason behind this is to make setup easier for newcomers and prevent the styling being used on unsupported players (because the plyr classname was used as a CSS and JS hook - which isn't ideal)

 ### Self hosting
 If you don't want to create a build system to include Plyr as an npm module, you can use the pre-built files. You have a few options:
 - Download the files from the CDN links above, they're already minified.
 - Download the files from [unpkg](https://unpkg.com/browse/plyr/dist/) or similar services.
 - Build the project yourself using `npm i && npm run build`, which installs the dependencies and spits out a build to `dist`.

 3. YouTube does not support programatically toggling the native fullscreen player via it's API. This means on iOS you have two options, neither being perfect:
 - Use the fallback/faux fullscreen option which covers the whole viewport (this is the default)
 - Set `playsinline` to `false` and/or `fullscreen.iosNative` to `true` - either option hides the fullscreen toggle in the UI (because of the above API issue) and means iOS will play the video in it's native player.

-```javascript

-const supported = Plyr.supported('video', 'html5', true);
+const supported = Plyr.supported('video', 'html5');
 ```
 The arguments are:
- Media type (`audio` or `video`)

- Provider (`html5`, `youtube` or `vimeo`)
+- Provider (`'html5' | 'youtube' | 'vimeo'`)
 - Whether the player has the `playsinline` attribute (only applicable to iOS 10+)
 ## Disable support programmatically
 The `enabled` option can be used to disable certain User Agents. For example, if you don't want to use Plyr for smartphones, you could use:
