cant get mig-21 to install in fc2

[ultramig688 2]

i have a question that involves installing the mig-21 bis in fc2 for those of you that have used modman this is going to sound like a dumb question.i want to install the mig-21 for fc2.so i downloaded the mig-21 and unzipped it and put it on my desktop. and it says to use modman so i downloaded the latest version 7.3.so far so good.when i click modmans mod installer it gives me a screen that says no addons avalible and since i have never used modman i have no clue what to do.eveything i,ve read says modman is easy to use to install mod.well i havn't seen anything about it thats simple because it never works for me.so can someone tell me what to do.

found the problem.i was trying to open the file after i unzipped the zip file.apparently modman uses the zip file (or RAR)file without unzipping it.works fine now
