+/// @brief   Demonstrates playing a video on FastLED.
+/// @author  Zach Vorhies
+///
+/// This sketch is fully compatible with the FastLED web compiler. To use it do the following:
+/// 1. Install Fastled: `pip install fastled`
+/// 2. cd into this examples page.
+/// 3. Run the FastLED web compiler at root: `fastled`
+/// 4. When the compiler is done a web page will open.
