 ## Why use encantar.js?
 
-* **Device-agnostic**: no need of AR-capable devices. encantar.js runs in all modern web browsers. It's AR built from scratch.
+* **Device-agnostic**: no need of AR-capable devices. encantar.js runs in all modern web browsers. It's AR built from scratch with computer vision.
 * **Fast and powerful**: encantar.js is GPU-accelerated. It uses WebGL2 and WebAssembly for turbocharged performance.
 * **No need to download apps**: encantar.js is a WebAR engine. Users can access the AR experiences immediately.
 * **Easy to get started**: encantar.js can be used with a `<script>` tag in your page. A static HTML page is enough to get started.

 ## What is WebAR?
 
 
     Fixing the orientation of the model is the preferred solution. However, you can also fix the issue with code: add a node (entity) to the scene graph and make it rotate its children by 90 degrees around the x-axis.
 
+## Can I increase the resolution of the tracking?
+
+Yes. You can increase the [resolution of the tracker](api/image-tracker.md#instantiation), as well as the [resolution of the camera](api/camera-source.md#instantiation), using the API. You can also increase the resolution of the rendered virtual scene by setting the [resolution of the viewport](api/viewport.md#instantiation). Performance is affected by various factors such as upload times (GPU). Test your AR experience on your target devices to find a good balance between performance and increased resolution.

 ## I am enchanted!
 
 I know! :wink:
