Well sometimes the docs are even hard for me to read with little mistakes.
But I find this function a very useful one, because maybe a person wants 30 bots on a 32 slot server, and a human wants to join.
Code:
When a human connects to the server, a bot is kicked to give the human a guarenteed free slot to play.
If you don't want that to happen, then I would suggest putting min_bots 30 or what ever amount of bots you want.
I think the docs are kind of for experienced pbmm users for like people who already know what is what but need specifics.
