add tutorials

Is your feature request related to a problem? Please describe.
The documentation can feel overwhelming for first-time users. A step-by-step, approachable examples for building common SaaS applications.

Describe the solution you'd like:
Adding simple tutorials for creating different types of SaaS apps would significantly improve the onboarding experience. These tutorials should include practical, hands-on examples with clear steps, such as:

Creating a Chat-Based Usage App
A guide for building a real-time chat application that demonstrates setting up a database, integrating APIs, and handling user interactions.

Building a Subscription-Based SaaS App
An example showcasing subscription plans, payment integration, and user management.

Launching a Data Analytics Dashboard
A tutorial on building a dashboard with real-time data visualization using modern chart libraries.

I think it can really boost repo, and make people get most value out of it

@haydenbleasel I feel that even before long tutorials , if we can have just smaller intro of running the project and what variables are strictly important to get the project running is more crucial . Once the project starts running then people can eventually figure out other things .
