Documentation Improvement: Add Examples for Common Use Cases

[tavigaussboy9]

Issue

The current documentation for the Identity Service does not provide concrete examples of common use cases. Adding examples would help users understand how to effectively utilize the service in real-world scenarios.

Suggested Improvements

1. Add Examples Section: Create a new section in the documentation titled 'Common Use Cases' that includes examples such as:

   • User registration flow
   • User authentication process
   • Token management and verification
   • Handling user roles and permissions

2. Code Snippets: Provide code snippets for each example to demonstrate how to implement these use cases using the Identity Service's API.

3. Error Handling: Include information on common errors users may encounter and how to handle them effectively.

Providing this information will greatly enhance the usability of the Identity Service and assist developers in integrating it into their applications.
