Well when they say read the manual they mean read the manual. It is in there. You can find it in the plug-in files you downloaded in the monster/docs folder. If you can't figure that out then here is Blatters online documentation;
http://www.ravenousbugblatterbeast.p...Docs/index.htm
Specifically read the section "User Guide". It explains it clearly there.
If you don't allready have it you will need the Admin All In One Commands plug-in found here;
http://forums.alliedmods.net/showthread.php?p=5109. This will gain you the amx_userorigin command. You will need it to get locations on each map for your monster spawn points.
Just follow the instructions in the "MANUAL" and you should be able to set up all of your maps.
A little advice. Check everything that came with your plug-ins for documentation first. Then open your plug-ins source or .sma file and look for information there. If you don't find anything come here and read the first post in the plug-ins support thread for possible author specific support sites or links to documentation. Then read the entire thread to see if your question can be found allready answered. The reason you were told to read the manual is because this has been gone over allready and the information you seek is in there. I know these threads can be rather long (if you think this one is long go look at CSDM) but that is in a large part due to people asking the same question over and over again and people get tired of answering the same thing repeatedly. Help all of the guys out here and help yourself.
