Updating readme.md

[kaamilmirza]

Issue:
The current readme.md doesn't provide an in-dept detail as to what folders of the code are meant for what purpose and generally what files are responsible for what kind of actions.

Solution:
In-dept summary based guide to project structure and general flow of the app.

I hope this message finds you well. I'm interested in learning more about your app. Could you please provide additional details about the README file that you are asking for? I’m planning to work on this issue.

Additionally, I have written some READMEs before, you might want to check them in my repos.
