Thanks @LecrisUT. I vote to the current theme.

The easiest way to integrate this is to delete this testing version and recreate it from this github organization.

I don't know well how readthedoc works. Does this mean the update of the documentation will be triggered from spglib organization?

+1 for the current theme (sphinx-book-theme)

So readthedocs automatically runs sphinx and it manages all versions internally. We can add this PR as is right now and then do the configuration after that.

@lan496 I've sent a request for the read the docs oauth, which should allow us to manage the webhooks automatically. Basically the setup and management are straightforward, we only need to setup the versioned documentation, otherwise everything is in the file of this PR.

@LecrisUT I've approved readthedocs.org.

Oh, it didn't get webhook privilege (actually good design). I've invited you, maybe you can add it:

GitHub incoming webhook -> Resync webhook

@LecrisUT I've resynchronized, which configured with status 200. Now it works?

Hmm, can you try to add it again? We were still getting issue:

The project spglib doesn't have a valid webhook set up, commits won't trigger new builds for this project. See the project integrations for more information.

Sure. I've added and resynced github webhook again.

Oh, it needed a bit of time to reset should be working now
