[ANN] a place to write/put ruby tutorials to help core docs!

I plan on announcing this more fully later, but here’s my attempts at
creating a repository for higher quality/tutorial like rdocs for the
core.

Feel free to check it out/add whatever you’d like there.

The thought is to have a high quality collection of rdoc supplemental
things there, then every so often convert them all to a gem [for easy ri
access] or commit them to ruby core itself.

I have found that having a reference like this is quite useful, and this
is an attempt to improve ruby’s documentation overall. Contributors
welcome :slight_smile:

Thanks!
