[Zope3-Users] What should I learn? [zope x3]

[emilian]

Hy,

I've started recently to have an interest in Zope (after working with
Plone a little).

Just as soon as I've started the Zope 2 Book, Zope X3 was released.

Now, as far as I see, Zope X3 seems to have a declared way of being
different from Zope 2.

So, what should I learn? I'm already trying to read the Zope 3 Book
(also read the small programmer's tutorial) and I find it quite hard.
There is some inherent assumption of Zope 2 programming that is not
the case for someone like me.

Am I supposed to read (and understand) the Zope 2 book and then move
to Zope 3 or should I stick to Zope X3 only?

Also, ZCML seems not documented very well. The MessageBoard example in
the Book has easy to understand code but the ZCML for it is rather
hard to get a grip.

Basically a step-by-step quide into Zope(X3) would be nice.

Thanks for any possible feedback,
Emilian
