Does TinaCMS work with existing HTML sites?

What I did not see in the docs is if TinaCMS requires a react application or work for editing existing html sites?

E.g. If I add the TinaCMS react script to an existing html page, then submit updates to my API, would this use case work?

Hi,

TinaCMS is mostly designed to work with (React) Components in mind, we have plans to support non-react websites, aka embed TinaCMS on your Hugo site for example and give you the ability to edit front matter and Markdown body à la Forestry.io. We did some early POC and we can get sidebar editing work, but you lose the ability to get real-time feedback, given you have to wait for the development server to update the preview.
