README is great for display, then gets a little less helpful

[geerlingguy]

The README seems to leave out a few details for all the features beyond the display—for example, the Touch panel section doesn't mention that you need to copy the compiled .dts to /boot/overlays, and then sections beyond that should probably at least still mention that you need to "Add the following to /boot/config.txt", just to be explicit about it.
