I am very interested in Digital Ocean’s “One-click install and deploy Ghost”, however I wouldn’t know how to update Ghost once it has been installed.

I could not find a tutorial here for that too.

I don’t want to install Ghost, buy and install a theme, then post to it like crazy only to be stuck on that single version from then on.

I’d rather build on Node.js and Ghost than PHP and WordPress… can someone please give me some guidance?

Cheers,
Tom
