There isnt a doc available yet, but there are two key properties. The first is, you can create mutable IPFS archives by generating a keypair; the pubkey becomes the identifier, and new versions are signed by the private key.

The second property is, you can use DNS TXT records to provide shortnames that map to the pubkey (or, I believe, to a static hash-id also). Run 'dig txt ipfs.io' to see an example.

EDIT: this is also helpful https://github.com/ipfs/examples/tree/master/examples/ipns

And it works really great! I've been serving my personal web page for months now at /ipns/pablo.rauzy.name :).

The only catch is that you need to republish regularly (I do it using cron two times a day) otherwise the IPNS do not work after some time, but I'm not sure it still is the case.

WOW, very difficult. Anyone have a link?

They talked a little about it in this video [1], but that's all I could find.
