FYI I haven’t started yet the HOWTO, it’s hard to find the time, there is a lot of things to do in the /e/ world. And I wait for the Windows 2004 update which bring Windows Subsystem for Linux 2 in order to see if /e/ can be built with that instead of a virtual machine (for those on Windows).
And sadly my HOWTO won’t be magical, the hardest thing will be to have a correct roomservice.xml file and it depends on devices so people will have to be on their own for this part.
It will come one day though
