Tutorial Blueprints?

Anyone know where I can find the documentation/a tutorial for …well…tutorial blueprints? My searches just bring up tutorials on blueprints, but I’m specifically talking about the “tutorial blueprints” at the bottom of the misc menu in ue4. Thanks in advance!

I remember downloading the Niagara example level in the Epic Launcher somewhere under the UE tab. I believe the blueprint tutorials should be somewhere there as well, if I understand you right.
