Confusing things:

Hope this is the best place to post this

Some confusing things as a newbie:

1.
For printScrollLeetSheet in leetsheet.html
How and where is the scrollleetsheet parser defined?
leetsheet.html does not actually exist in the codebase files

2.
How will users fork, share and save data.
Right now, it's a bit confusing: Do i clone scroll or scrollhub or PLDB ? What are these "folder" things ?
Once cloned, it still doesn't "work out the box" the leetsheet page for instance throws a GET error
Assuming this is because i do not have a server running, is there a way to have a Progressive web app that starts a js express server (assuming node and express are installed, and if not prompts to install them)

3.
How will private versus public auth work ? (i.e some information i might want to use scroll to consume, but not share)
