I've never used it, the man page says:


4. A manifest is created that contains information on the store paths, their eventual URLs in the cache, and
   cryptographic hashes of the contents of the NAR archives.

and the example pushes it up to the server ?
           $ nix-push \
               http://foo@bar:server.domain/cgi-bin/upload.pl/cache \
               http://server.domain/cache \
               http://foo@bar:server.domain/cgi-bin/upload.pl/MANIFEST \ << url where to put it?
               $(nix-instantiate foo.nix)

So I guess it's handled automatically..
