-## Status LED Cycle
+## Blink RGB Example
 
+The ESP32 core includes an example for cycling an RGB LED like the one found on this Thing Plus so long as the board variant defines it as `RGB_BUILTIN` (which ours does). Navigate to the example by going to **File** > **Examples** > **ESP32** > **GPIO** > **BlinkRGB** like the screenshot below shows:

+Select the board (SparkFun ESP32-C6 Qwiic Pocket or ESP32-C6 Dev Module until the Thing Plus is added to the espressif boards package) and Port and click "Upload". After uploading you should see the STAT LED on the board turn on full white, turn off, and then cycle through red, green, and blue repeatedly.
 
 !!! note "USB CDC On Boot Settings"
 
     Take note of the option labeled "USB CDC on Boot" when selecting the Board from the Tools menu. This option sets the serial outputs and defines their label for use in code. The SparkFun variants default to Enable USB CDC on boot which sets both <code>Serial</code> and <code>Serial0</code> as available serial ports. In this configuration, <code>Serial</code> corresponds to the direct USB/Serial converter on the chip (and the USB-C interface) and <code>Serial0</code> corresponds to the UART0 bus (default pins are 16 and 17).
 
-    With either setting, <code>Serial1</code> is available and refers to the UART1 bus (default pins are 4 and 5).

 ## Installing espressif Arduino Boards
 
 !!! important
-    As of this board's release, espressif is currently working on an update to v3.0.0 for their Arduino boards package to include the Thing Plus - ESP32-C6 as a board variant (among other updates). Unfortunately, as of this writing, this version does <i>not</i> include the Thing Plus ESP32-C6 and is also in alpha phase at the moment so installing this package requires a few extra steps. Open the preferences menu by navigating to <b>File</b> > <b>Preferences</b>. Look at the bottom of the Prefences menu for "Additional boards manager URLS" and then copy this JSON link into that field:
-    https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json
+    
+    As of this writing, the Thing Plus ESP32-C6 is awaiting approval to be included in the alpha version of the ESP32 boards package (3.0.0-alpha2 currently) so it is *not* included in the alpha install but we're hoping it gets added very soon. We'll keep an eye out for the next update (whether it be to alpha or a full release of v3.0.0) and update this page once it is out.

+As mentioned above, the espressif ESP32 Arduino Boards package should soon include the Thing Plus - ESP32-C6. In the meantime, users can get most of the functionality from this board by selecting either the "SparkFun ESP32-C6 Qwiic Pocket" or the "ESP32C6 Dev Module". The Qwiic Pocket will have things like the Qwiic/I<sup>2</sup>C bus tied to the same pins as the Thing Plus.
