I figured out how to get the mod working.
1. Open Steam, go to Library, scroll down to Tools, and install Source SDK Base 2013 Singleplayer.
2. Open gameinfo.txt in the mod's directory.
3. Erase all the text in gameinfo.txt, and paste this text into it: Pastebin.com
4. Save gameinfo.txt and restart Steam.
5. Korsakovia will appear in your library, you can launch it and play the mod.
