I followed the Jekyll Bootstrap instructions.
I already had a GitHub account (barely used).
I checked out the basic repository into a folder in my Dropbox. That way I will have a backup of the whole blog and can tinker with it whether in work (Windows) or at home (Mac).
I would like to be able to blog using Emacs.
I’ve got this initial blog post up from a Windows machine and without installing Ruby on it since the page processing is all done server-side.
