Extrepo is a specialized tool in Debian (sid) for handling adding external repos in a safe and secure way. Might be useful for a bunch of tutorials in our documentation:
a Torproject repo - which I haven’t checked yet but may be a more direct way to obtain newer TBB releases.
That’s apparently just the “normal” https://deb.torproject.org/torproject.org/ with its “usual” contents. I.e. no Tor Browser as Debian package.

As far as I understand, extrepo doesn’t invent its own software. It’s not a kind of flathub. extrepo is a tool to make adding repositories such as https://deb.torproject.org/torproject.org/, https://download.docker.com/linux/debian, https://dl.winehq.org/wine-builds/debian, etc. easier. Kinda a way to upload an APT signing key to Debian and /etc/apt/sources.list.d drop-in configuration snippet by sending a pull request to the extrepo-data repository.
