first of all, we need the game to run and meet the minimum system requirements:
OC : Windows® XP/Vista
Processor : 2 GHz Processor or better
Ram : 4 GB Random Access Memory
Videocard : 512MB dedicated VRAM or better
DirectX : 9.0c Version
Internet : optionally
HDD/SSD memory : 5 GB
sound card : DirectX® 9 compatible
And very important: MOUSE, Keyboard (OPTIONAL) , Monitor.
If your computer is playing solitaire, Purple Place ,poker, or opening a tab in your browser, then you can start playing GMOD

It should be understood that it is necessary to click on the PLAY BUTTON!!

OTHERWISE, THE GAME WON'T START!

If fortune smiled on you and you are the lucky one who managed to start a new game, then let's proceed to the last step.
Don't click anything yourself! Follow the guide or your game might explode! .
Now, without touching the keyboard...carefully pick up the COMPUTER mouse, and drag it forward

CONGRATULATIONS, YOU'RE THE HERO JOHN!! YOU'VE MADE IT! WRITE TO YOUR FAMILY, GRANDMOTHER, MOM, FRIENDS AND LOVED ONES THAT YOU DID IT! NOW THEY WILL DEFINITELY BE PROUD OF YOU!
