Managing Hugo from two different systems?

Ouch! Yeah, git can be a pain to get into. As an alternative, you could try and play around with putting your site code into Google Drive / Dropbox or a similar service. I haven’t tested this personally, so I would be curious about the workflow if you did decide to try and were able to make it work.

Edit: Here’s a post about using Dropbox / IPhone. I use neither, so not personally tested.
