 ==== Changing a branch name
 
 [CAUTION]
-----
+====
 Do not rename branches that are still in use by other collaborators.
 Do not rename a branch like master/main/mainline without having read the section "Changing the master branch name".
-----
+====
 
 Suppose you have a branch that is called _bad-branch-name_ and you want to change it to _corrected-branch-name_, while keeping all history.
 You also want to change the branch name on the remote (GitHub, GitLab, other server).
