Now that the legacy branch is set up, you can make changes in your local repository.

Creating a new branch

Starting in the CanJS repository you have cloned to your computer, you can create a new branch:

git checkout -b your-branch-name 3.x-legacy

Replace your-branch-name with the name of your feature branch, e.g. git checkout -b html5-fix to create a html5-fix branch.

Submitting a pull request

Once you’ve made your changes and run the tests, you can push your branch to GitHub:

git push origin your-branch-name

Make sure you replace your-branch-name with the name of your branch. For example, git push origin html5-fix.

Next, submit a pull request and set the "base" branch to 3.x-legacy.
