Thanks for sharing this content! It's very helpful.

In https://github.com/chiphuyen/machine-learning-systems-design/blob/master/content/design-a-machine-learning-system.md, "Machine learning project flow" leads to a 404.

Thanks for letting me know. The chapter was designed to be used with magicbook, so the images show up for the PDF version here. I'm not sure how to make it appear in both the raw markdown version and the PDF version. If you do, please me know. Thank you!
