For people who are beginners at commands and scripting in CS:GO. (This is Steam Version)
1. Copy and Paste the lines of text underneath into a notepad (or notepad++!) document.
2. In the document, navigate to the top left. Click "File" then Save As.
3. On "Save as type:" select "All types (*.*)". On "File name:" name it whatever you want, but add ".cfg" without quotation marks directly after the name is put in. Now click "Save" and remember, put it somewhere where you'll remember it.
4. Navigate to your cfg folder: "C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\cfg" for me.
5. Put the config (.cfg) file inside the cfg document.
6. Start up CS:GO and open an offline server. Next, open up console and type in "exec <cfg_file_here".
Congrats! You made it!
