So how the fuck do you install this shit?
TL:DR version is below!!!!!

Go to your steam folder. It can be anywhere and nowhere, depends really. It's common in your (C:), and (D:). 

Once you've found your "Steam" folder, navigate to \Steam\steamapps\common\Counter-Strike Source\cstrike\maps

When you're in that last folder, "maps", you will see all the default maps, and some of your own if you use hammer. Anyways, drag your BSP-file
and have it unite with it's new family. Once they have greeted and had they tea, you can go in game type "map aim_nostril_v3" in the console.
You don't have to move this file "readme you shits" anywhere. Just leave it all alone. Unless you want it to keep its friend, you can move that
too but it won't change anything. File lives matter.

You're done diddely done!
