Install /e/ on device currently running Android 10 (specifically samsung s9)

Yeah @luka,
the S9 ‘starlte’ /e/ documentation leaves a lot to be desired.Among other things, it only talks about »custom recovery - you can download TWRP«

Not a single syllable is mentioned about eRecovery, although a separate eRecocery version irecovery-e-0.13-q-20210120 s provided for the current /e/ OS ‘Q’ build e-0.13-q-20210120

The same applies to eRecovery for the Galaxy S9+ star2lte Does eRecovery not deserve to be mentioned? This is incomprehensible to me!
