instructions for manual install:

1) open Fallout4/data

2) copy meshes folder in the data folder

3) choose which plugin/s you want and copy them in the data folder

you can choose one of these: "Bigger 1", "Bigger 2", "Bigger 1sa", "Bigger 2sa, "Height limit + attack spawn points" or "Height limit only"

or you can create merge of plugins you want from "separate plugins for manual install" and pick what you want
and than use this mod: http://www.nexusmods.com/skyrim/mods/69905/? to create merge so you dont have 20 separate plugins,
but only one.
