SDK Installation

Availability

The Source SDK is freely available to all owners of Valve's core Source games. For a list, see this page.

Downloading and Installation

To install the Source SDK:

1. Open the Steam window.
2. Click on the Tools tab.
3. Double-click on the Source SDK entry.
4. The Source SDK will then be downloaded to your computer via Steam.

Once it has been fully installed, you will be able to launch it in the same way you installed it (from the Tools tab).

You can also create a desktop shortcut for the Source SDK by right-clicking on the Source SDK entry and clicking Create desktop shortcut from the context menu.

Note:For the SDK to function correctly, it is important that any games you wish to edit are fully up-to-date. You can make sure of this by running the game before launching the Source SDK. Simply launching the game then quitting after you get to the main menu is sufficient.
