pmbootstrap config ui sxmo
Alternatively, you may download a PostmarketOS image with Sxmo preinstalled (equivalent to running
pmbootstrap init and selecting
sxmo as the interface): 
Note that Sxmo is designed for the Pinephone, so don't expect all the button mappings, gestures, or config scripts to work well on any other device.
Refer to the userguide for detailed usage instructions.
