How does all this work?

Hi all! Hoping someone can point me in the direction of how things work here on PeakD. This is my first introduction to the HIVE blockchain and trying to figure it all out. I looked for some kind of documentaion on PeakD but not seeing anyting on the site. Realizing there's a lot here and really have no idea what everything I'm looking at means and how to interact with PeakD. Anyone know if there's some documentation I can read or some good articles for getting started here and learning about the community?

Thanks!
