using this with an NAF project?

The readme is a bit sparse. Was planning to use hubs-based Janus-NAF setup with our project, but am considering giving this a try instead.

We are using easyrtc adapter and NAF right now. I'm trying to roadmap a transition to a mediasoup SFU swap in instead.

(1) I don't see any 'adapter' for NAF; do we just use the Janus adapter? Is this designed to be a drop-in replacement for the api it was using?
(2) Does one need to use the hubs-fork of NAF (also, where is that?)
(3) If one gets this repo up and running, this is the mediasoup server, right? It's not 100% clear what this repo is; the janus plugin repo was just a plugin you build and add to an existing running janus server, but I don't know how the plugin system works for mediasoup, and I'm thinking this repo probably is the whole SFU server...? Is that right?
(4) What changes in the readme if I'm running this for me? I assume, for example, that I can't use your SSL certs? Do I need to generate my own? Info about that? Etc.

Thanks!

Start with the README and the repository's setup information. Clarify whether the project is the complete mediasoup SFU, how it relates to NAF and its adapters, whether the Hubs fork is required, and how users configure their own deployment and SSL certificates. Done means the README answers the four questions with actionable setup guidance.
