I am having significant headaches trying to get through this section. Please see my post to other forum:

It looks like a great tool, and I would like to try it out for possible use. But I could suggest cutting this section out, or possibly putting it as an appendix, since it appears to be incidental to the purpose of the getting started guide.
I will skip it for now, of course, but it is not clear to me whether I have a bad configuration that will give me trouble later in the tutorial.
