Took a while to get this thing running. For anyone wondering, I'd been searching for some headless CMS (a content management system that would make it easy to write and edit posts) for a while. I didn't want anything PHP based, and I didn't want to run through a bunch of terminal commands to install it. Most important of all, I wanted some easy mobile editor so I could write on the go.
Turns out I just went with Semplice, which is a WordPress variant, which runs on PHP. I'm running Semplice 5 and I've been pleasantly surprised at it's ease of use. So far so good.
