Unreal Tournament Editor: GenerateProjectFiles errors missing module "Social"

I used the git client to clone the repository, and followed the instructions to the letter. It gives the error below when running “GenerateProjectFiles.bat”, and Engine/Source/ThirdParty is indeed missing “Social”.

Binding IntelliSense data... 96%ERROR: Couldn't find module rules file for module 'Social'.

You can go to the linked page and read detail information.

Ah thanks I missed that section!
