I need some help with spawning the bots

[ilikevalvegamesokay]

So, uhm, i haven't played Counter-Strike 1.6 in a while, and wanted to play again lately. I reinstalled zBots, but when i went to play with them, i couldn't remember the command to spawn them! I tried bot_add, but nothing happened, i tried any of the other commands in the main page but none of them spawned them either.

And i just can't remember what the command was. Please help.
