[Twisted-Python] Beginners Guide to Twisted Anywhere?

[Britt Green]

I'm wondering if there exists a beginners guide to using Twisted.
Something similar to the online tutorial for Python. I've browsed the
docs on the Twisted website, and haven't been able to find what I'm
looking for. Specifically, a lot of the examples are mostly just code
with brief commentary which doesn't really explain things.

Can someone help me out! :)

Many thanks,

Britt
