 [The ZMK documentation](https://zmk.dev/docs) covers both basic and advanced functionality and has a table of OS compatibility for keycodes. Please note that the RGB Underglow, Backlight and Power Management sections are not relevant to the Advantage 360 Pro's custom ZMK fork. For more information see [this note](#note)
 
-There is a web based GUI available for editing the keymap. It is available at https://kinesiscorporation.github.io/Adv360-Pro-GUI. This repository is also compatible with certain other web based ZMK keymap editors however they may have keycodes or behaviours that are not implemented on the 360 Pro and could cause unusual behaviour or build failures. Furthermore changes made on other keymap editors may not be compatible if one goes back to using the Kinesis GUI.
+* If you would like to continue using GitHub we recommend using Nick Coutsos’s keymap editor: https://nickcoutsos.github.io/keymap-editor/.
+* If you would prefer to leave GitHub and firmware flashing behind you can perform a one-time firmware update to gain access to Clique. Get started here: https://kinesis-ergo.com/360p-clique-upgrade/.
 
 Certain ZMK features (e.g. combos) require knowing the exact key positions in the matrix. They can be found in both image and text format [here](assets/key-positions.md)
