Standardize the install instructions across the apps #3064
Description
Is your feature request related to a problem? Please describe.
Currently, the installation steps differ across the applications in this repo.
Describe the solution you'd like
I propose creating a single, standardized installation guide that applies to all apps. We can then reference this central guide in each application's README to ensure consistency and reduce duplication.
Describe alternatives you've considered
Leaving the instructions as they are, but this leads to drift where some apps have outdated or incorrect setup steps compared to others.
Additional context
This aligns with the discussion in #2956
