Currently, there is no info how to reach and edit this document.

@ShalokShalom is the Background Information page sufficient for this issue? What else do you feel can be added to make it more clear/useful?

How is it about a screencast, which shows all the steps?

In addition to the background information page linked above, there's also the Customization section which tries to layout the steps needed to make changes.

Is there a specific spot you are getting hung up on or not sure what to do?

This is all on Github. This issue here is about all the homepage.

My apologies, I misinterpreted the suggestion.

I think you're right; there should be some more details/resources added to the website.
