+---------------
+==== DELETE REMOTE BRANCH ====
+Your local Git keeps a list of remote branches under ''remote/origin/*'', you can see it with:
+<code bash>
+git branch -a
+git fetch -p  # Remove any stale references from your local list that no longer exist remotely
+</code>
+Delete remote branch:
+<code bash>
+git push origin --delete <branch-name>
+</code>
+---------------
+==== ACCIDENTALLY COMITED ON MASTER ====
+If changes were accidentally committed on ''master'' and we want to move them to a new branch:
+<code bash>
+git switch -c new-branch         // Creates a new branch and switches to it.
+git checkout master              // Go back to master
+# Cleaning master - Option 1
+git reset --hard origin/master   # This will delete the commit from master,
+                                 # but it still exists on new branch
+                                 # Resets to match the remote branch exactly.
+                                 # Used to discard all local commits since last fetch/pull
+# Cleaning master - Option 2
+git reset --hard HEAD~1          # Moves one commit back in local history.
+                                 # Used to undo the last local commit (or a few with HEAD~2)
+# Bonus - local history in compact form
+git log --oneline master
+</code>
+---------------
+==== SQUASH ====
+Scenario - you would like to "squash" several commits in your branch before submitting the merge request, so that all your changes look like a single commit.
+**Step 1** - Find the **base commit** where your branch diverged from main
+<code bash>
+git merge-base master HEAD
+</code>
+**Step 2** - Start interactive rebase from that commit:
+<code bash>
+git rebase -i abc123
+</code>
+**Step 3** - In editor which will open, change all but the first pick to squash or just s:
+<code bash>
+pick abc123 My first commit
+squash def456 My second commit
+squash ghi789 My third commit
+</code>
+**Step 4** - Editor will open again for a commit message. Edit as you wish.
+**Step 5** - Push with force:
+<code bash>
+git push --force
+</code>
+**Step 6** - When trying to pull after these changes, you might need to rebase:
+<code>
+git config pull.rebase true
+git pull
+</code>
+==== CHANGE COMMIT MESSAGE ====
+If the commit has been already pushed to the upstream, and it's the latest commit:
+<code bash>
+git commit --amend # edit the commit msg
+git push --force
+</code>
