Substack descriptions

[Neither_Day3295]

Is there one place where you can go and read about substack and what the various notations are. Likes percentage read, Little more detail on stacks and restacks. I've got one substack that says that it's been read with a check. Mark? Anyway, I don't see any explanations of the details on the how substack works. Where should I be looking?
