Added full reset instructions to begin anew, quick setup instructions, enumerated minimum dependencies, and everything should be good to go factually. It's now a matter of how to present the information.

Should I unwrap the herefile script?

[adamoutler]

@frenck what are your thoughts on the herefile versus single-line explanation? Should it be a commented script put in here or multiple breaks? As it stands, it is the cleanest format as the set -e prevents further execution if a command fails. The user may then look up the problem. If they copy-paste blocks, as one does, without the wrapping, execution continues until the end with invalid values. Are you sure you want it unwrapped? The wrapping in this case prevents continuing execution after failure.

I already gave feedback on that above.

I'm ok with this PR (language/content-wise). However, as said, I'm the proud owner of no-Windows enabled machines for 13 years already. The factual content has to be verified and approved by someone else.

Does this still need to be reviewed?

[adamoutler]

Yes.
