* Create a new product at https://launchpad.net/products/+new
* Do the bzr init; bzr add *; bzr commit -m "first commit" dance
* put your SSH keys on to your Launchpad profile page
* bzr push
sftp://<launchpadid>@bazaar.launchpad.net/~<launchpadid>/<productname>/<branchname> (For example sftp://dholbach@bazaar.launchpad.net/~dholbach/killerapp/dev or sftp://dholbach@bazaar.launchpad.net/~dholbach/killerapp/newfeature)
Apart from that you will probably need bzr add, bzr rm, bzr diff, bzr
log, bzr status, bzr inventory, all of which bzr help or bzr help
<command> will help you with. Or check out

If you need anything else, let me know.
Have a nice day,
