Never modded before, advice how to get started?

Ok yea that’s something I need to learn about lol. Those things sound familiar just from using Skyrim mods from Nexus years ago, some bug reports would say things like the data tables had conflicts etc… I could roughly understand what they were saying lol. From what I understand many things in the game (objects, NPCs, items etc) have attribute/stat tables and are all assigned an ID. So some mod authors will reference tables when introducing new items or even share stats for like-items. Tell me if I got that remotely right lol :confounded:
