   - `Canonical Contributor Agreement`_
 
-* Get your changes into a local bzr branch.
-  Initialize a repo, and checkout trunk (init repo is to share bzr info across multiple checkouts, its different than git):
+* fork from github, create a branch and make your changes
+  - ``git clone https://github.com/cloud-init/cloud-init.git``
+  - ``cd cloud-init``
+  - ``echo hack``
 
-  - ``bzr init-repo cloud-init``
-  - ``bzr branch lp:cloud-init trunk.dist``
-  - ``bzr branch trunk.dist my-topic-branch``
+* Check test and code formatting / lint and address any issues:
 
-* Commit your changes (note, you can make multiple commits, fixes, more commits.):
+  - ``tox``
 
-  - ``bzr commit``
+* Commit / ammend your changes
+  Before review, make good commit messages with one line summary
+  followed by empty line followed by expanded comments.
+  - ``git commit``
 
-* Check pep8 and test, and address any issues:
+* Push to branch to github:
 
-  - ``make test pep8``
+  - ``git push``
 
-* Push to launchpad to a personal branch:
+* Make a pull request.
 
-  - ``bzr push lp:~<YOUR_USERNAME>/cloud-init/<BRANCH_NAME>``
-
-* Propose that for a merge into lp:cloud-init via web browser.
-
-  - Open the branch in `Launchpad`_
-
-    - It will typically be at ``https://code.launchpad.net/<YOUR_USERNAME>/<PROJECT>/<BRANCH_NAME>``
-    - ie. https://code.launchpad.net/~smoser/cloud-init/mybranch
-
-* Click 'Propose for merging'
-* Select 'lp:cloud-init' as the target branch
-
-Then, someone on cloud-init-dev (currently `Scott Moser`_ and `Joshua Harlow`_) will 
-review your changes and follow up in the merge request.
+Then, someone on cloud-init team.
 
 Feel free to ping and/or join #cloud-init on freenode (irc) if you have any questions.
