- git branching
Trunk branch Every Git repository has a trunk (also referred to as main, mainline, or the master branch). When a Git repository is created, the trunk exists automatically as the implicit first branch. The use of a trunk and the timing of changes landing on it vary depending on the exact branching strategy being used. In trunk-based development, the trunk is the central branch to which all developers send their code changes.
