 ## Installing espressif Arduino Boards
 
-!!! important
-    As of this board's release, espressif is currently working on an update to v3.0.0 for their boards manager with support for the Qwiic Pocket Development Board - ESP32-C6. This release is in alpha phase at the moment. Open the preferences menu by navigating to <b>File</b> > <b>Preferences</b>. Look at the bottom of the Preferences 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
-
-    Click "Ok" and then open the Boards Manager tool, search for "espressif ESP32" and install the latest alpha release (3.0.0-alpha2 or later). This install process may take some time but when it completes, you can select "SparkFun ESP32-C6 Qwiic Pocket" as the board to upload code to the Qwiic Pocket Development Board. We'll keep an eye out for the full release of v3.0.0 and update this page once it is out.
