+## Bonus Tip: Making Amendments to Commits ##
+
+If at any point you want to undo something due to a mistake such as, forgetting to add some files or messing up the commit message you can use `--amend`.
+If you just want to edit the commit message it can be done with the following command:
+
+```console
+git commit --amend
+```
+
+Running this single command will take your staged files and use it for the commit but open the commit-message editor to change the commit message. 
+The commit made using `amend` will **overwrite** the previous commit so you must be very careful.
+Additionally, if you want to add files you forgot to stage then you want to add this to the commit:
+
+```console
+git commit -m 'initial commit'
+git add forgotten_file
+git	commit --amend
+``` 
+
+The previous, commit will be overwritten and you will end up with a single commit. 
+It is important to note that `ammend` does not fix the previous commit it effectively replaces it, as if the previous commit never happened.
