By default, Git Town does not push new feature branches to the origin remote since that would make creating branches slower and triggers an unnecessary CI run for a branch containing no changes. Running git sync or git new-pull-request will push the branch to origin later. If you prefer to push new branches upon creation, set this option to true by running:

git config [--global] push-new-branches <true|false>

The optional --global flag applies this setting to all Git repositories on your machine. Without it, this setting applies to the Git repo you are in.
