This game is so poorly documented it's unreal. It's like Bethesda had all of these whacky ideas and then just expected people to fully know them all. I had to resort to Youtube a couple of times when I got stuck. I still don't bother modding much (just scopes to guns and so on) and I've built about three walls and a chair for some old grunter just because I had to. Therefore the Mechanist DLC left me cold (because it was about three crap quests and then more building) but Far Harbor was absolutely fantastic. Hoping Nuka World (confirmed now) is good because apparently it's the last DLC. Bit of a con that, two proper map DLC and the rest were all just stupid add ons.
