Where to put new files:

• New files should go into a top-level subfolder, named after the article slug. For example: my-awesome-article

How to merge your changes:

1. Make sure the CI code style tests all pass (+ run the automatic code formatter if necessary).
2. Find an RP Team member on Slack and ask them to review & approve your PR.
3. Once the PR has one positive ("approved") review, GitHub lets you merge the PR.
4. 🎉

@adyouri Hey, I did some minor changes to reflect the post-TR udpates. Hope you don't mind!

Thanks @bzaczynski,

I was just about to ask you if it's alright for me to start working on these updates! :)

I am so excited to finally see the tutorial live!
