+Everyone was in this situation at some point. You wasted a days worth of work by accidentally deleting a branch. But, all hope is not lost! Git never forgets. 
+
+Every action, be it committing changes, deleting or switching branches, is noted down by Git. To see your latest actions, you can simply run `git reflog` (It's pronounced `ref-log` but `re-flog` sounds just as reasonable):
+
+```
+5704fba HEAD@{45}: commit: docs: update changelog
+b471457 HEAD@{46}: commit: chore: refactor binop checks in parse_expression
+5f5c5d4 HEAD@{47}: commit: fix: struct imports
+76db271 HEAD@{48}: commit: chore: fix clippy warning
+ac3e11c HEAD@{49}: commit: fix: circular imports
+0cbdc88 HEAD@{50}: am: lexer: handle ' or " within the string properly
+27699f9 HEAD@{51}: commit: docs: spec: add notation
+```
+
+Commits in Git are just data that is not associated by anything. If you accidentally delete a branch, the commits will stay where they are, and you can reference them directly. To recreate your deleted branch, simply run this command:
+
+```
+git checkout -b <branch> <sha>
+```
+
+And that's it! Your branch is restored. Remember to commit early and often, or prepare to loose your work!
