How to Install :
Download the zip archive.
Copy the zip file in your data/script/ directory. Usually : C
:\Games\Toribash-3.91\data\script
Extract the archive.
DO NOT EXTRACT in a new directory : you have to use the "Extract Here" option, and not "Extract to atmo.2.1.0/". So after that,
if you don't have a folder named "atmo" in your "data/script/" folder, you did something wrong.
Launch TB and type in the console :
/ls atmo/src/setup.lua
You should see a message saying installation is finished, and that you must restart TB. If not, you did something wrong, post here the error you get, and I'll try to fix it.
So, restart TB. You can now launch the Atmospheres menu by typing in the console :
/atmo
