Started NDoCH wrap-up post

Hi all, I gave this a start and mostly stole all the wording from @elauervose 's emails/Google doc. Unfortunately, a couple of the image links on the Google doc took me to dead Dropbox pages, but I added the ones that worked.

I'm out of time for the night, but I thought I'd put this up and let y'all ( @CodeForPortland/owners ) have at the branch (and do whatever you want to it). 

Thanks!
