Improve Quick Start Example

[rogstrix-acer]

Problem

The current Quick Start explains how to install and start runapi, but new users would benefit from a fully working minimal example that can be copied and run immediately.

Expected Behavior

A beginner should be able to:

• Follow the Quick Start
• Run a minimal API
• Understand the project structure

Suggested Approach

• Add a minimal CRUD example
• Ensure all commands work end-to-end
• Mention required Python version

Difficulty

Easy
