Ubuntu Wiki

To enable you to do most of the tasks listed, you are going to need to have an Ubuntu SSO account. This will enable you to login to Launchpad in order to push code, the wiki for editing, the QA trackers for reporting - in fact all of Ubuntu's infrastructure is available to you with this account.

Ubuntu SSO/Launchpad Login

To create your account go to the login page and enter your details. Follow the instruction you will receive in your confirmation e-mail.

Once you have confirmed your SSO account, go to the Launchpad login page and complete your Launchpad account.

Git

Information about setting up Git can be found here

Launchpad and Bazaar

So you can pull code and push when you are ready, you will need to upload an SSH key and integrate bzr with your local machine. Details for doing both of these can be found on the QA Team Tools Setup page.

Information related to working with branches on Launchpad can be found here.
