[Jason Porter]

Good feedback, thanks Dan. I can work on improving along those lines. 

Anyone else have ideas or a +1 for what Dan suggests?

They will be the base for our getting started guide for Seam 3. The pages are backed by an example that can be checked out and built (possibly broken right now, I haven't tried to build / run it for a while).

For instance, you do a nice job explaining the purpose of the BOM and the need for the Java EE APIs as a provided scope dep. I also like that you forewarn the developer of potential missteps to prevent them from tripping up early on and getting discouraged.

At first glance of the index, we see that the tutorial is structured based on the activation of Seam modules (i.e., configuration). Each section begins with dependency configuration, followed by configuration for activating features of Java EE or a Seam module. As a reader, I'm looking at this saying "wow, all I'm doing is configuring stuff"...and that leaves it being very dry. I don't think this is the right way to structure it.

Rather, what we want is, "I want to write code, stop me when I need to configure something so I can continue writing code." and "How am I doing?" We need to feed the reader those rewards and assurances.

If a developer wants to see just the instructions for how to activate a Seam module, that's what the reference guide is for. Here we need to be in a flow. You should try to show code first, then show the configuration to activate it (unless you need the API deps, then maybe switch it) and finally, tell them how to run the application at that stage.
