Hey there!

From a quick glance, it seems that page is for CHICKEN 4 (the current 
version is 5). I think the only differences from that page are that 
instead of `use` you should now use `import`, and that the `numbers` egg 
is no longer needed to have a full numeric tower support.

As far as a "full" tutorial goes, I'm not in on it, but someone else may 
give you some help on that front.

For differences between C4 and C5 you may want to take a look at this[0] 
page. Some other possibly useful links are The Manual[1] and the 
documentation[2] for the core language and all the eggs.

Hope this helps!
