Sure, why not? I have a couple of questions following a list of observations.

The About page says it’s a Java Spring Boot application, though… so the Go component is limited to a federation service?

The docs are all stub pages, so it’s a hard to figure out what it’s all about, and the Demo link leads to a standard Lemmy instance, complete with “Support Lemmy” hamburger menu entry. What’s differentiating this project, and what’s the motivation?

So of the projects under the github umbrella is the federation service (which you clearly state is the problem domain of this component). There’s quite a bit of scaffolding in that project; is the issues list of (8 currently) enhancements the sort of thing you’re looking for help with?
