-# Welcome to the AI-Powered Registration System Pilot Project!
+# Welcome to the AI-Powered Registration System prototype!
 
-**Note**: This project is a self-initiated pilot by Lorentz Yeung and is not affiliated with any organization.
+Data quality issues have long plagued council databases, burdening W2 workflow teams (e.g. the Assisted Travel Team's dashboard I am working on), data analysts, and engineers with manual cleaning and validation. This pilot explores how AI-driven workflows can address these pain points by streamlining user registration, ensuring accurate data collection, and reducing validation overhead.
 
-This initiative explores the capabilities of AI-driven workflows to streamline user registration, focusing on efficient data collection and validation. The system uses a stateful LangGraph workflow to guide users through a dynamic registration process, inspired by modern conversational interfaces.
 
 ## What is the Registration System?
-This application leverages FastAPI, LangGraph, and AI validation (DSPy/ChatGPT with Guardrails AI) to collect user information (email, name, address, phone, username, password) with optional fields and real-time validation. It ensures accurate, formatted data storage in a PostgreSQL database.
+This application leverages **FastAPI**, **LangGraph**, and **AI validation** (**ChatGPT** with **Guardrails AI** and **dspy**) to collect user information (email, name, address, phone, username, password (included only a few for demo purpose)) with optional fields and real-time validation.  It uses real-time validation to enforce formats (e.g., addresses, phone numbers), minimizing errors and enhancing data integrity stored in a PostgreSQL database.
 
 ## How Does It Work?
 - **Register**: In the "Registration" tab, users answer a series of questions, with optional fields (address, phone) skippable.
-- **Validation**: AI validates inputs (e.g., lowercase emails, standardized phone numbers).
-- **Data Storage**: Responses are saved securely in a database for review and editing.
+- **Validation**: AI validates inputs (e.g., e.g. address formats, phone numbers, will ask for clarification if ambiguous).
+- **Data Storage**: Responses are saved securely in a database for review and editing (currently in a PostgreSQL db in another server.).
 
 ## Objectives
-- Assess AI-driven validation for accuracy and user experience.
-- Enhance efficiency in user onboarding processes.
-- Explore scalable, secure registration systems for public sector applications.
+- Address **data quality** issues by automating validation and reducing errors.
+- Enhance **efficiency** in user onboarding processes.
+- Explore **scalable**, secure registration systems for public sector applications. The Same logic could apply to Copilot's Agent, and Power Apps.
 
-## Pilot Program
-We encourage users to test the system with varied inputs to evaluate its robustness. Your feedback is vital for improving this pilot.

-## Registration Process
-
-This tab guides you through a streamlined registration process. You'll be asked a series of questions to collect your information, including email, name, address, phone, username, and password. The address and phone questions are optional and can be skipped.
-
 ### How to Use
 - Answer each question in the provided text box.
-- For optional questions (address, phone), check the "Skip this question" box if you prefer not to provide the information.
-- Input formats:
-  - **Address**: Include house number, street, town/city, and postcode (e.g., 123 High Street, London, SW1A 1AA).
-  - **Phone**: Use 10 digits for landlines (e.g., 020 123 4567) or 11 digits for mobiles starting with 07 (e.g., 07700 900 123). Avoid +44 formats.
+- Check the "Skip this question" box if you prefer not to provide the information.
+- 
+
 - After completing all questions, review your data in the summary and edit if needed.
 - Use "Next Registration" to start a new session or "End Session" to reset.
