+# Trading Web Application README
+
+Welcome to my Trading Web Application! Below is an overview of the application's architecture, technologies used, and instructions for setting up and deploying the application.
+
+## Overview
+
+My Trading Web Application is built using ASP.NET on the server-side with AzureSQL for database management. On the client-side, I have utilized Node React with TypeScript. The application allows users to perform stock trading activities and manage their transactions efficiently.
+
+### APIs
+
+I utilize third-party APIs for fetching live stock prices and other indicators for trading. Due to cost considerations, I have opted for the Yahoo Finance API, which provides live stock prices using stock symbols, and the Google API for retrieving stock names.
+
+## Server
+
+### Technologies Used
+- ASP.NET for developing APIs using MVC controllers
+- Entity Framework for CRUD operations and data management
+- AzureSQL for database storage
+
+### Features
+- Utilizes MVC architecture for API development
+- Provides RESTful APIs for user management, stock trading, and transaction records
+- Easy data migration with Entity Framework for updating data schema
+
+## Client
+
+### Technologies Used
+- Node React with TypeScript for front-end development
+- React for state management and user interface development
+
+### Features
+- Challenges with type checking due to TypeScript
+- Responsive user interface to handle user responses and errors effectively
+- Utilizes React for state management, including user input validation before sending data to the server
+- Implements cookie-based authentication to reduce the need for repeated sign-ins
+
+# <span style="color:red">START APPLICATION</span>
+
+### For Client
+
+1. Install Node Modules: npm install
+2. If Using Visual Studio:
+- Simply click start or use `dotnet run`
+
+### For Deployment
+
+1. After installing node modules, build the app: yarn build
+2. Configure the startup file to point to the `dist` index HTML for deployment.
+
+**Note**: Configuration files or startup instructions might be highlighted in red for better visibility.
