Which files I need to edit to enable a faction?

I have followed the rough steps from here

and added my own effects in the effect tables and the effect junctions, adding council and ruler name in the loc files, but the faction I wanted to appear as playable in main campaign doesn't appear.

I wanted to make available the other Briton and German barbarians, since other culture group have at least 2 other factions.

Thank you for your help!

I've found how to enable factions other through guides (I guess I haven't look at every guide).

However, I have a related question about factions (I'm avoiding to make too many threads).

As desert nomadic faction, they have eastern buildings. The temples are giving eastern culture influence, not desert nomadic so that results in public order decrease. Is it possible to change the effect of buildings to the matching faction's culture?
