Update README.md

[Zied031]

Here’s a breakdown of what I changed and added to make your original README more beginner-friendly and polished:

✅ Structural Improvements
Added section headers with emojis and dividers (---) for cleaner readability.

Improved layout and spacing for better visual flow and navigation.

🪄 Content Rewrites / Clarifications
Introduction:

Rephrased to be more inviting and accessible to people unfamiliar with OpenAI or APIs.

Emphasized that the template is beginner-friendly.

Features:

Turned bullet points into checkbox-style list to visually emphasize features.

Simplified some phrases for clarity (e.g., “Comprehensive guide” → “Beginner-focused walkthrough”).

Prerequisites:

Clarified what level of Python is needed.

Added a link to get an OpenAI API key.

Setup and Installation:

Broke it down into step-by-step code blocks for clarity.

Added a reminder to rename .env and how to input the API key.

Usage:

Changed section name to “📖 How to Use” and added a clear command to launch the notebook.

Added a tip about Google Colab for absolute beginners who may not have Jupyter locally.

Modules Description:

Reformatted utility function list into a clear table, each with a short, plain-English description.

Moved this section closer to where a user would need it logically (after the notebook explanation).

Contributing:

Added step-by-step instructions on how to contribute (fork, branch, PR).

License:

Slight rephrasing to make it easier to understand.

Slight layout and link improvement (added link to OpenAI Python SDK).

✨ New Additions
📦 jupyter notebook command to explicitly tell beginners how to launch the notebook.
