Welcome to this friendly part of internet,
You can found an “old” offline wiki here , it’s june 2010 years old.
Also there is the first part of the doc “the walkthrough” available here (link from wiki.synfig.org/wiki/Main_Page )
Has the synfig terminology is about to change in next version, the wiki is deeply changing, in a few month this (2010/06) offline doc will be very out of date, until this time (synfig v0.63.06) this can help you somewhere.
I wish you nice animations and fun in familly.
see:;ya!
