+Palette 2 multimaterial support - provides a tighter integration
+supporting Palette 2 devices in connected mode.
+
+This modules also requires `[virtual_sdcard]` and `[pause_resume]`
+for full functionality.
+
+If you use this module, do not use the Palette 2 plugin for
+Octoprint as they will conflict, and 1 will fail to initialize
+properly likely aborting your print.
+
+If you use Octoprint and stream gcode over the serial port instead of
+printing from virtual_sd, then remo **M1** and **M0** from *Pausing commands*
+in *Settings > Serial Connection > Firmware & protocol* will prevent
+the need to start print on the Palette 2 and unpausing in Octoprint
+for your print to begin.
