3. Install Garry's Mod: Once purchased, go to your Steam Library, find Garry's Mod, and click 'Install'. Follow the on-screen prompts.
4. Install Required Source Games: Garry's Mod utilizes assets from other Source engine games. For the best experience and to avoid missing textures/models, it is highly recommended to install and run at least once:
