Personally, I'd prefer the installation instructions and perhaps a list of (what appears to be a tremendous amount of) POI's for us to go visit.
We could then have a little treasure hunt discovering the fruits of your labour and there's always Wikipedia if we want more info. Extensive background info will, I'm sure, be of interest to some, but it may perhaps not be the best use of your time to replicate what's already out there. Perhaps a "Useful links" section in the docs for those that do want to research further?
Can't wait for this. It looks stunning - a huge well done and thanks to all involved.
