you have a lot of tutorial requests - what is one already-developed and approved tutorial that we can work with to ensure your standards?

We wanted to give people lots of options for hacktoberfest :)

One tutorial that is solid is the "getting started" tutorial on this library. that's a good guide for the type of thing we're looking for - something easy to follow.
