How do I set up a git repository?

Great to see that LP now supports git. So much so that we'd like to port our codebase over to git from bzr. Unfortunately, I'm a little confused on how to do it, as the instructions at https://help.launchpad.net/Code/Git seem to be missing some key information.

I have a bzr repo which lives in a place something like this: lp:~<team>/<team>/<name-of-private-repo>/

I wish to convert the repo to git, so as specified in the 'Converting from bzr to git' section, I did the following:

$ cp -r trunk/ master
$ cd master
$ git init .
$ bzr fast-export
$ bzr fast-export --export-marks=../marks.bzr | git fast-import --export-marks=../marks.git
$ git add .
$ git ci -m "conversion to git"
$ rm -rf .bzr

And it's at this point that I'm not sure how to proceed.

I've already added the following to my ~/.gitconfig:

[url "git+ssh://<email address hidden>/"]
        insteadof = lp:

[url "git+ssh://<email address hidden>/~autonomouse/+git/"]
        insteadof = lpme:

So how do I get the new git repo onto Launchpad?

Do I push back to the same repo?
$ git push --set-upstream lp:~<team>/<team>/<name-of-private-repo>/ master

Trying this gives me "fatal: remote error: '~<team>/<team>/<name-of-private-repo>' is not a valid Git repository path."

Was I supposed to push to a new subfolder?
$ git push --set-upstream lp:~<team>/<team>/<name-of-private-repo>/master master

I get the same "fatal: remote error: '~<team>/<team>/<name-of-private-repo>/master' is not a valid Git repository path."

Or am I supposed to set up a new repository for the git code? But attmepting to do so presents no option for specifying the new repo as a git repo. Besides, this isn't what I want to do - I want to convert the existing repo over to git.

I've also tried with a test repo but got "fatal: remote error: Project '+junk' does not exist."

Please advise.

Thanks
