+The stats component displays a UI with performance-related metrics of your Aframe Project. The stats component applies only to the [`<a-scene>`][scene] element.
 
 ## Example
 
 ```html
 <a-scene stats></a-scene>
 ```
+It can also be written as `stats="true"` which will activate the UI and `stats="false"` to hide the UI. This version can be useful during development as it allows you to keep the component within your code for easy access. 
 
 ## Metrics
 
 - **fps**: frames per second, framerate. Aim for stable 90 fps with the WebVR 1.0 API.
 - **requestAnimationFrame** (raf): Latency.
+
+Three.js -- **Memory**
 - **Textures**: number of three.js textures in the scene. A lower count means
   the scene is using less memory and sending less data to the GPU.
 - **Programs**: number of GLSL shaders in the scene.
 - **Geometries**: number of three.js geometries in the scene. A lower count
   means the scene is using less memory.
-- **Vertices**: number of vertices in the scene.
-- **Faces**: number of faces in the scene.
+
+Three.js -- **Render**
+- **Points**: number of points (vertices) in the scene.
+- **Triangles**: number of triangles (faces) in the scene.
 - **Calls**: number of draw calls on each frame.
+
+A-Frame
 - **Load Time**: how long it took for the scene to start rendering, in ms.
 - **Entities**: number of A-Frame entities.
