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. 🎉

Thanks for also providing the HTML file. That's the perfect fallback in case installing PyICU doesn't work.

As optional improvements, you may consider:

• Adding a note to the Readme about the problems of installing PyICU (similar to your paragraph in the tutorial)
• Providing two requirement files and Jupyter notebooks the materials. One that contains the PyICU parts, and one that doesn't. But personally, I think the HTML file is a good solution for any installation issues.

@acsany Okay, I've added a side note about the potential hurdles with installing PyICU and where to find more help.
