This setting stores the name of the main branch. The main branch is the default parent branch for new feature branches created with git hack and the default branch into which Git Town ships finished feature branches.
The best way to change this setting is via the setup assistant. Git Town commands also prompt for this setting if needed.
In the config file the main branch is part of the
main = "config-main"
To configure the main branch in Git, run this command:
git config [--global] git-town.main-branch <value>
--global flag applies this setting to all Git repositories on
your local machine. When not present, the setting applies to the current repo.
