 ## Oculus Rift and HTC Vive Support
 This plugin leverages the [webvr-boilerplate](https://github.com/borismus/webvr-boilerplate) project (which in turn uses [webvr-polyfill](https://github.com/borismus/webvr-polyfill) and [three.js](https://github.com/mrdoob/three.js)) to create a 'responsive VR' experience across multiple devices.
 
-Oculus Rift and HTC Vive playback requires Firefox Nightly with the WebVR addon, or experimental WebVR-enabled builds of Chromium. Go to [WebVR.info](http://www.webvr.info) for more info.
+Oculus Rift and HTC Vive playback requires Firefox >= 55, experimental WebVR-enabled builds of Chromium, or via Chrome by enabling webvr in `chrome://flags`. Go to [WebVR.info](http://www.webvr.info) for more info.
 
 GearVR playback requires the latest Samsung Internet for Gear VR with WebVR support enabled. Go [here](https://webvr.rocks/samsung_internet) for more info.
 
 ## Accessing the Camera Position
 The Three.js rotation values are exposed under the property `cameraVector` on the `vr` plugin namespace.
 
-For example, assuming the parent element for Video.js is `#video-container` the following code would return the current `cameraVector` values:
-
-    document.getElementById('video-container').player.vr.cameraVector
+```js
+var player = videojs('my-video');
 
-See `example-camera.html` for a working demo that logs camera object and rotation to the console every second.
+player.vr().cameraVector;
+```
 
 ## Accessing THREE.js objects
 The Three.js Scene, renderer, and perspective camera are exposed under the `threeJs` object as the properties `scene`, `renderer`, and `camera` on the `vr` plugin namespace.
 
-For example, assuming the parent element for Video.js is `#video-container` the following code would return the current `camera` object:
+```
+var player = videojs('my-video');
+
+player.vr().camera;
+player.vr().scene;
+player.vr().rendeer;
+```
+
+## Options
+### `forceCardboard`
+> Type: `boolean`, default: `false`
+
+Force the cardboard button to display on all devices even if we don't think they support it.
+
+### `projection`
+
+> Type `string`, default: `'auto'`
+Can be any of the following:
+
+#### `'360'` or `'Sphere'`
+The video is a sphere
+
+#### `'Cube'`, `'360_CUBE'`, or `'equirectangular'`
+The video is a cube
+
+#### `'NONE'`
+This video is not a 360 video
+
+#### `'AUTO'`
+Check `player.mediainfo.projection` to see if the current video is a 360 video.
+
+#### `'360_LR'`
+Used for side-by-side 360 videos
+
+#### `'360_TB'`
+Used for top-to-bottom 360 videos
 
-    document.getElementById('video-container').player.vr.threeJs.camera
+### `player.mediainfo.projection`
 
- while:
+> type: `string`
 
-    document.getElementById('video-container').player.vr.threeJs.scene
+This should be set on a source-by-source basis to turn 360 videos on an off depending upon the video.
 
- would return the THREE.js Scene, and:
+See [`projection`](#projection) above for information of values. Note that `AUTO` is the same as `NONE` for `player.mediainfo.projection`.
 
-    document.getElementById('video-container').player.vr.threeJs.renderer
+### `debug`
 
- would return the THREE.js renderer.
+> type: `boolean`, default: `false`
 
+Enable debug logging for this plugin
