If that's an option I haven't found it from a quick glance on the website. I just followed what was there without looking too deeply into it. Maybe if that's something you can do, there should be a clear process written up somewhere
I've only scanned the "how to build" documentation but from what I saw there is only information on producing a test network not joining the public blockchain? Is there a set of instructions for hosting your own "real" node?
(I've not read the white paper or other documentation so the info may be buried in there, I'm unlikely to find time for that in the near future though so asking out of "laziness" in case you have a quick answer to give)
