In the Contributing to the Unreal Engine | Unreal Engine 5.2 Documentation section it suggesting to stick to master branch for contributions.
BUT master branch is actually a branch for UE4.27, for Unreal 5 main branch is ue5-main please add some kind of note about it or replace master with ue5-main in this article completely - I’ve spent hours downloading and compiling from master branch just to learn it’s not Unreal 5.
