How to export and rehost your Tumblr site
3.2.0 of Jekyll looks like it's breaking a few things, so I've changed the guide to make you specifically install the version I was using,
3.1.3. I believe this is the issue: jekyll/jekyll#5145.)
You will be using
jekyll-import to export your Tumblr site, Jekyll to (re)create it, and Surge to rehost it.
Update: You can also use Tumblr's native export feature in your blogs' individual settings. But rehosting that might be tricky. Read my comments below this post for how that works.
