How to Fix 'You have divergent branches' in Git
What Git is warning about and how to choose merge, rebase, or fast-forward behavior.
Git is telling you the local and remote histories both moved and it needs guidance on how to reconcile them. The right next step depends on your team's merge or rebase policy.
Avoid This
Do not guess your team policy on shared branches if rebasing could surprise others.
Do not suppress the warning globally without choosing a workflow intentionally.
Save commands, add notes, and build a Cheatbook with the fixes you want to keep handy.
