Im kind of confused.
Is this CM Partner?
If its not, can it be use with CM Partner?
This is not CM Partner.
That mod adds NPCs which are specifically scripted to be companions.
Companion Share and Recruit lets you recruit EXISTING npcs as companions.
So you can make friends with anyone in the game and take them adventuring.
It also has a really slick real-time orders system and they are smart enough to automatically heal each other, loot and so-forth.
It might be slightly confusing...not sure what would happen if you 'recruited' an existing CM Companion...but it's supposed to be compatible to quote the author
"The mod is built for compatibility and flexibility, and will work alongside any and all companion mods, overhaul mods and so on, as well as allowing custom companions to be created with the minimum of effort."
