+/// @file    Wave2d.ino
+/// @brief   2D wave effect demonstration
+/// @example Wave2d.ino
+///
+/// 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.

+/*
+This demo is best viewed using the FastLED compiler.
+
+Windows/MacOS binaries: https://github.com/FastLED/FastLED/releases
+
+Python
+
+Install: pip install fastled
+Run: fastled <this sketch directory>
+This will compile and preview the sketch in the browser, and enable
+all the UI elements you see below.
