-/* INSTRUCTIONS
- *
- * 1. First Run the 'ESP32 Sketch Data Upload Tool' in Arduino from the 'Tools' Menu.
- *    - If you don't know what this is or see it as an option, then read this:
- *      https://github.com/me-no-dev/arduino-esp32fs-plugin 
- *    - This tool will upload the contents of the data/ directory in the sketch folder onto
- *      the ESP32 itself.
- *
- * 2. You can drop any animated GIF you want in there, but keep it to the resolution of the 
- *    MATRIX you're displaying to. To resize a gif, use this online website: https://ezgif.com/
- *
- * 3. Have fun.

- * Below is an is the 'legacy' way of initialising the MatrixPanel_I2S_DMA class.

- * By default the library assumes a single 64x32 pixel panel is connected.
- *
- * Refer to the example '2_PatternPlasma' on the new / correct way to setup this library
- * for different resolutions / panel chain lengths within the sketch 'setup()'.
