Is your blog open source? I tried to implement Tina for my personal blog but I found their docs to be pretty confusing (granted this was a few years ago) and had a hard time upgrading due to breaking changes. I personally ended up going with Contentlayer in the end which wasn't what I wanted, but it's good enough without breaking changes.
Also, if it's helpful, I actually live-streamed my implementation and luckily a Tina maintainer was in the chat when I also struggled with the docs:

I’ve used it in prod before. It’s fine for small, focused sites. For example, I have some lists of people who journalists can contact. It uses decap to let editors manage the lists.
I did! I used to work at Netlify heh. I liked it but it was a bit too clunky for what I wanted (I admit I haven't tried it since Decap took over though).
