+## Default branch
+
+When you create a new [project](../../index.md), GitLab sets `master` as the default
+branch for your project. You can choose another branch to be your project's
+default under your project's **Settings > General**.
+
+The default branch is the branched affected by the
+[issue closing pattern](../../issues/automatic_issue_closing.md),
+which means that _an issue will be closed when a merge request is merged to
+the **default branch**_.
+
+The default branch is also protected against accidental deletion. Read through
+the documentation on [protected branches](../../protected_branches.md#protected-branches)
+to learn more.
