Welcome to Source Modding

Welcome to Source Modding where you can discover tutorials covering how to develop for Valve’s Half-Life SDK (GoldSrc), Source SDK, Game Authoring Tools and the recently released Half-Life: Alyx Workshop Tools

You will find an ever growing collection of useful information here, everything from in-depth tutorials from the ever generous Source Modding Community, to tools, community links and history regarding everything Valve related.

Let me know via E-Mail if you have any suggestions, requests or ideas for improvements.

The website & Collection is under active development, expect non critical bugs, half finished pages and some weird stuff here and there,

I have just added the Source 2 Tutorial Section and will soon populate it with tutorials for Dota 2 & Half-Life: Alyx.

Thank you for visiting Source Modding, I hope you find the collection useful.
