ADManager Plus users

ADManager Plus users

Newbie here.  Just had this project, to implement ADMP in our environment and create processes around user administration mostly.
I find that the ADMP documentation is very heavy on the sales side of things (how ADMP can cut your repetetive admin tasks) but extremely light on the how to side of things.
I'm currently trying to figure out the users inside ADMP itself and why, when I modified some users, they got moved into the Direct Users group in ADMP.
Every time I search for users or ADMP users or users inside ADMP, all I get is articles on how to manage the AD users, not the ADMP users, if that makes sense.

Not sure if it's difficult because I don't know what to search for, or if it's difficult because it is, indeed, difficult to find what, why, how, etc of this tool.
