Example Project for latest "Lightweight Rigid Body Simulation"

I’ve got about 5 minutes of experience using Unreal Engine. In other words, no experience. I was drawn to it by news of “Rigid Body Simulation” and a demonstration video of the same on the front page. This is particularly interesting to me and I’d like to learn more about it. Is that particular example project or other similar rigid body simulation projects available for download somewhere?

An example would be nice, just starting to look into this…

I would also like an example on this one. I know is related to the rigid body node within the animation but I’m unsure how it’s used.
