Thanks @ChrisAldrich. @_am1t has a very detailed writeup too. I'll find some time to go through it. @_am1t I'd be grateful if you have your Hugo site template public somewhere. I don't intend to copy it wholesale.

Thanks. I hadn't yet read your post then. Now that I have, I see that you already had linked your theme in there. Though, I couldn't locate the JS you referred. Not at a computer at, so will look at your theme more carefully later. Also, do we need JS,if Hugo has getJSON tmpl fn?
