Dyndolod improve these, so the stuff far from you won't looks ugly as hell. what the heck is LOD? Level of Detail, it is a technical term that refer to the detail of objects rendered at far distance. If you don't need those kind of mods then you don't need these.
There are however several mod-addons that you gotta have depending on the mod you want to install, namely FNIS for adding custom animation, Dyndolod for generating LOD, Bodyslide to change character body shape or clothing's body shape.The only tool I will ask you to use is simply ModOrganizer2 (MO2).

If you look at most other guides - MO2, 圎dit, BashPatch / MatorSmash, MergePlugin, LOOT. Let's start with tools, what program you need to mod your game.
