Welcome to SourceModding where you can learn how to use Valve's Source SDK to modify the stock games or create your own. You will find a wealth of useful information here, everything from indepth tutorials, tools and websites. The Website and tutorials are an ongoing project of mine and i hope to keep them available to you as long as possible. Let me know via email, or through the Forum if you have any suggestions, requests or improvements.
The website is under active development, expect non crucial bugs, half finished pages and some weird stuff here and there, I am a one man army and try to work on the site when i have time :) - Cathal 30.01.2015
