Note for next time: Let's try and avoid & in branch names because it is a special character that needs to be escaped when working with git, I had to escape the & to checkout this branch - https://docs.github.com/en/get-started/using-git/dealing-with-special-characters-in-branch-and-tag-names#naming-branches-and-tags

Fixed alignment and reviewed, one small thing to take care of, rest all looks good.
