Currently you can only try it by building it yourself, instruction here. https://codeberg.org/solver-orgz/treedome/src/branch/master/docs/building.md
But .deb and nixpkgs update is planned to follow suit though! You can also try an outdated one in https://aur.archlinux.org/packages/treedome-bin.
Tell me what you think about it!
Oof. I hope you’re locking the file when one client opens it, then, else you’re going to have people inadvertently wrecking their data.
The project page says you’re using sqlite, though, which should already support multiple clients. Are you just completely rewriting the database instead of using transactional updates?
