[Drop Dead Studios] Spheres of Might Open Playtest

[Milo v3]

i hear good things about this and SoP, and i am a big fan of offering my players options.
But i tried to check out the test documents in the OP and honestly, i do not know where to start or how this works.

Is there an ''Explain it like im simple'' page i can start? How the system works, what the classes are, that kinda stuff? because even the ''small'' rules doc is 25+ pages and i feel a little lost in it all.

is there a starters guide to SoM? :D

Simplest way to describe it would be.

Take one of the SoM classes (they're all in the class docs)/an archetype (conversion doc)/or a feat (probably the rules doc, been a while so not 100% on this one), and you get talents. Talents are separated into groups called spheres. SoM users have a thing called focus which they can expend to boost some talents.
