+- To Revert/Recall Changes:
+    - IF LOCAL CHANGES, NO COMMIT MADE.
+        - These can be in two stages:
+          - Staged / Unstaged : Difference between them is have you added them or not.
+            If added using `git add` command, then staged, otherwise unstaged.
+          - Now for any local changes in staged section, ideally should be brought to unstaged section
+            before removing it.
+          - Command
+          ```
+          # particular files
+          git reset HEAD <file1> <file2>
+
+          # all files
+          git reset HEAD
+          ```
+        - Once local changes in unstaged section, you can remove these changes:
+          - Command
+          ```
+          git restore <file1> <file2>
+          # or
+          git checkout <file1> <file2>
+          ```
+    - IF COMMIT MADE, BUT NOT PUBLISHED
+        - If you want to keep the changes just want to do some edit.
+          - Command
+          ```
+          # from hash, if you want to go back to a particular commit use its hash
+          git reset --soft 0bfabb11a8ce2b61dbf204ee3bc55ba58df354fd
+
+          # from count from top, replace 2 with count of top commits you want to remove
+          git reset --soft HEAD~2
+          ```
+        - If you dont want to keep the changes just clean.
+          - Command
+          ```
+          # from hash, if you want to go back to a particular commit use its hash
+          git reset --hard 0bfabb11a8ce2b61dbf204ee3bc55ba58df354fd
+
+          # from count from top, replace 2 with count of top commits you want to remove
+          git reset --hard HEAD~2
+          ```
+
+    - IF COMMIT MADE, AND PUBLISHED
+        - If there are more people working on it use revert. Which will create a rollback commit aswell.
+          - When we do revert changes of those commits removed and get staged for the commit to imply removing these changes.
+          - Command
+          ```
+          # From particular hash to head rollback, to that particular hash comit all above commits will be removed.
+          git revert --no-commit 0bfabb11a8ce2b61dbf204ee3bc55ba58df354fd..HEAD
+
+          # If you want to revert by count from top, replace 3 by count number
+          git revert --no-commit HEAD~3..HEAD
+          ```
+
+- If anything unwanted happened and too much of confusion with commits or reverts or anything:
+      - Simple stash the unsaved changes and do `git pull`
+      - It will bring your local syste to repository git status.
+- To pull changes after commit, therefore always do, `git pull --rebase`, it will bring your commit on top
+  of other commits and then do `git push origin`
+
+
+- Stash: We use stash for saving our local changes so that we can pull or work on different commmits
+    - Command
+    ```
+    # To Stash
+    git stash
+
+    # To view a particular stash
+    git stash show -p stash@{1}
+
+    # To apply a particular stash
+    git stash apply stash@{1}
+
+    # To apply top Stash
+    git stash apply
+
+    # To apply and remove top Stash
+    git stash pop
+
+    # To drop a particular Stash
+    git stash drop stash@{1}
+
+    # To see stash list
+    git stash list
+
+    # To clear stash list
+    git stash clear
+    ```
+
+- Check git logs:
+    - Command
+    ```
+    # Git check all logs, use q to exit, if logs are more than screen size and down button to explore all
+    git logs
+
+    # to view top x logs, replace 5 with x number in the below commands.
+    git logs -n 5
+
+    # To check log graph and its branches in detailed manner
+    git log --graph --oneline --decorate --all
+    ```
+
+- To cherry pick a commit:
+    - Command
+    ```
+    # Go to branch from where you want to pick
+    git checkout branch_name
+
+    # View its commits
+    git log
+
+    # Go to original branch
+    git checkout original_branch
+
+    # cherry pick commit
+    git cherry-pick commit_id
+    ```
