Good tutorial. I did not know that I need to add text about my custom map in Gamemodes.txt every time I add a map. I added demiragecsgo and copied the deoffice text. So Now when I start the game I have two "deoffice" maps to choose from. The latter one is my demiragecsgo map. Is it possible to get the game to show the mapname correctly? Iguess its the imagething I need to change. IF somebody knows how to add maps so they have their real name ingame please help.

man great job I thing . To be honest i didn't understand all things but what I want is I have some downloaded maps from this site and I want to know how I can play it in various mods thx buddy

I wouldn't mess with this, because when people download your map there is no way that file is gonna be edited for their csgo install in their gamemodes text. So why bother to do this unless your just testing your map before release because I'm sure in the final version of csgo there will be some automatic easier way to designate which gamemode the map is in if its custom.
