• Review current ReadMe and identify improvements and updates for a better "Getting Started" experience.
• Update FAQ : https://drive.google.com/drive/folders/1QjWJJoE4lNMiK8TJ5CtdmwYaxpj5KecV for most often asked questions and issues

This is a great idea. 👍 Perhaps a README (re)structure like this can help:

1. Organization (example)
2. Aim/Purpose (example)
3. Visuals (example)
4. Instructions (example)

(From my notes, with all credits going to @mroker242.)

@LakshmiLavanyaKasturi: Could we verify if this is already taken into account with docs.hiro.so nav-flow redo?
