Thanks @MikiPAUL! I'm going to pull this PR locally and work on it a little too, so let me know if you are planning to edit it further so I can wait and avoid merge conflicts.

Otherwise, I'll push my additions in the upcoming week or so, and we can go over it together! Looking forward to iterating with you, and thanks again for authoring this contribution ❤️

Hi @MaryaBelanger, I have made some updates to my pull request. I have fixed the typo. Please take a look at the pull request and I'm new to open source please let me know if you have done anything wrong.

@MikiPAUL I had to make some changes to adhere to our formatting and style guidelines, and I needed to create a new PR to do so. I need to close this one now, but I have added you as an author on the new PR, so you'll get authorship credit when it merges! Thanks for getting this started!
