No problems, I can see one or two bits that I think could do with clarifying (not least to get rid of emacs :P ). I'll have a go at it this evening and take notes.
The particular editor isn't all that important. You could just use nano or vi. I don't think any of the instructions contain anything really Emacs specific.
I happen to use Emacs and the source for the site is an org-mode document, which makes editing it very easy. Exporting it as HTML is a few key presses.
As a vi user, i'd be willing to leave the great war to one side and give nano the thumbs up, many people not used to the console struggle to quit out of vi or emacs while being competent with sublime text or notepad++. nano works better for them.
