I have just started playing around with Squeak, and I am duly
impressed... with just about everything except the state of
documentation. Every detail seems to be covered somewhere, but I am
looking for some overview. I found a helpful book ("Squeak" by Xavier
Briffault, in French), but there are still open questions.

For example, before I start any serious project, I would like to be
sure that I don't loose my work due to stupid mistakes, careless
import of code, a system update, or whatver else might happen. I have
seen plenty of references to file ins/outs, changesets, projects,
etc., but I don't really know what I should use in which circumstances
or for what purpose.

A related problem is the evolution of the whole system. There seem to
be neither "undocumented" nor "officially documented" parts in Squeak.
So if I want to make sure that my code will still be useful next year
in Squeak 42.7, what can I safely rely on?
