Ubercart

I am brand new to Ubercart - just started reading and attempting to install this afternoon.

However, reading this page:

http://drupal.org/project/ubercart

I get one set of module dependencies for Drupal 6, and reading this page:

http://www.ubercart.org/docs/user/3313/installing_ubercart

I get a different set of module dependencies.

Additionally, the wording on that 2nd link seems to indicate that these instructions are for Drupal 5, and the Drupal 6 release is not available yet, nor any documentation...

To further confuse me, only one of the second link's required modules are available for Drupal 6.

So, I need to ask:

1. Is Ubercart only stable as a Drupal 5 solution?
2. Is the documentation just out of date?
3. What documentation is recommended for Drupal 6 users?

I hope my post reads as the interested supporter, and not some whiner... I am loving Drupal and the fantastic community. Ubercart really appears to be great, if I can just find the right set of instructions...
