Well, I wouldn’t say that the problem is lessened by a list on the Github, it was just me happy that it even exists. All because oftentimes there is simply no meaningful documentation behind some things I have to work with :)
It will probably be easier if there was default “simple registration mode”, where it just guides you through registration on one of the static or random “general purpose multilingual instance”. And “advanced mode”, where you are supplied with lists and you are on your own.
