Documentation for new `orb.checkpoint.v1` missing

[PhilipVinc]

Hello,
it appears to me that the new interface has been released, but the documentation and all notebooks in https://github.com/google/orbax/tree/main/docs/guides/checkpoint/v1 are not hoooked up in the documentation.

Is the interface actually public?
Could you link and publish those docs?

Hi, we are not aiming to officially publicize and release V1 until we have had a chance to do some integrations with some customers, fix bugs, improve reliability, and make any necessary API tweaks.

That said, V1 is fully functional with most of the documentation in place, and few API changes expected, so you are free to use it if you choose and we would welcome any feedback you have.
