Amazing work @tancnle and really clever use of markdown to its full potential. Would love to seem more of those mermaid charts in later documentation.

Left a few Nitpick suggestions around grammar and formatting for you to consider, but will approve in the meantime

Looks good @tancnle! Another area for me to learn about :)

👋🏼 @macite I would also love your input into this strategy 🙏🏼

@tancnle this looks good. It needs some details on the costs, challenges, limitations etc, and how these would be addressed. It would be good to have a presentation on this when all of the details are together.
