Installation for beginners:

1. Open up "Steam\steamapps\common\Counter-Strike Global Offensive\csgo\cfg"
2. Create a blank text file.
3. Open the text file and paste the script into it.
4. Rename the text file to autoexec.cfg (show file extensions in Windows first!)
5. Open steam.
6. Go to Counter-Strike: Global Offensive > Properties > Set launch options.
7. Add "+exec autoexec.cfg" in the end without quotes (").
8. Open console and type "exec autoexec.cfg"
If you already have a config you can just copy the code to it.

This is a remade version of the original script by Skazzy3. I changed a couple commands, fixed a couple issues I had with it, so this version is error-proof and comes directly from the video.
