Hi @chitvs, and thank you very much for this improvement!

Unfortunately, I don't have time for a full review right now, cause I'm on vacation in your beautiful country (mostly in Liguria FWIW).

Your changes look good at first glance except

• You shouldn't render out the newsfragments yourself, we only do that ourselves when releasing a new version of the framework. Could you undo this part?
• I would prefer to link from the FAQ to the tutorial, not the other way around.

Btw I don't know if you are participating in Hacktoberfest, but this is already good enough to qualify, I'll add the label just in case.

Sure, I will change that. (btw I'm from Italy so have a nice weekend there!)

Yes I'm participating, thanks!

I did all the changes requested, when you have time take a look but imo now should be good.

Thanks, this LGTM bar a couple of very minor nitpicks that I can address in another PR.
