+  <h1>Vision Camera playground</h1>
+
+  <h2>Overview</h2>
+
+  <p align="left">
+  This is a demo application featuring some of the many features of the Vision Camera:
+
+  * Photo capture
+  * Video capture
+  * Flipping device (back camera <-> front camera)
+  * Device filtering (ultra-wide-angle, wide-angle, telephoto, or even combined virtual multi-cameras)
+  * Format filtering (targeting 60 FPS, best capture size, best matching aspect ratio, etc.)
+  * Zooming using [react-native-gesture-handler](https://github.com/software-mansion/react-native-gesture-handler) and [react-native-reanimated](https://github.com/software-mansion/react-native-reanimated)
+  * Smoothly switching between constituent camera devices (see [demo on my Twitter](https://twitter.com/mrousavy/status/1365267563375116292))
+  * HDR mode
+  * Night mode
+  * Flash for photo capture
+  * Flash for video capture
+  * Activating/Pausing the Camera but keeping it "warm"
+  * Using the Example Frame Processor Plugin
