@metalbiker you don't need an /e/ account. I'd tested /e/ few months ago but finally installed #LineageOS. Now it will be no longer mantained for my device, but /e/ is (so far), so this weekend I'll make this transition.
The instructions are pretty clear and they are copy/paste from lineageos wiki
I didnt use before because it comes with #microg installed by default and some other apps I didnt like
