To give analogy in software development, I don't want to know how to build an app, I want to know what are the tools to build the app and why.
E.g. use IntelliJ for text editor because it's an IDE (Why IDE is important? Why not Notepad?), use Ngrok for tunnel (why?), use Charles for proxy (why?), use PostgreSQL for DB storing relational data (why? what's relational?), use Redis for caching (why?), etc.. you get the idea.
