you take a feat that gives you stuff related to other classes (multiclass archetypes) or just more specialized stuff.
some of them require certain things, like the wrestler dedication feat requires you to be at least trained in athletics, or like the new necrologist, that requires you to be a spellcaster that can cast summon undead
and then there are class archetypes (not to be confused with multiclass archetypes), which are subclasses you take at level 1 and at 2nd level you have to take the archetype’s feat
and like prestige classes, they seem to add a bunch of archetypes every new book they release, which is not at all an issue because that means MORE OPTIONS! and i love that
yeah sounds a lot like pf2e archetypes.
