The funny thing is that I got my information from the UE4 documentation and the UE wiki: > **[Online Subsystem Steam](https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Online/Steam/)** > > An overview of Online Subsystem Steam, including how to set up your project for distribution on Valve's Steam platform. > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline.
