[support] Drupal 8 how to

[Roger]

Drupal 8 = $wow.
Have used Drupal 6 and 7 and am building a test events bookings site in 
Drupal 8 beta because I am accustomed to models views controllers way of 
doing things from Angular and Rails plus the added advantages of HTML5 
and CSS3 are obvious.  Creating modules seems easier to me, I never got 
the hang of hook_something_alter.

1. Tutorials
I've run into problems with tutorials about creating D8 modules. While 
all essentially say the same thing, none actually work, all tuts give 
YAML syntax errors.
Where can I get tutorials that actually work and don't shut down the 
site? Even the latest ones on Lynda.com seem out of date.

2. Forms
Forms in Drupal can be very long 10-20 fields and difficult to reformat 
and no way I can find to reference the form instance id to enable 
breaking the form into small field sets.
How can a form be broken into several sections/pages to lead the person 
completing the details through a couple of fields at a time?

3. Are there any example tuts for sending payment to a bank without 
using ecommerce modules?

Thank you for any assistance, it's much appreciated.
