+# Product List
 
 This project has been created by a student at Parsity, an online software engineering course. The work in this repository is wholly of the student based on a sample starter project that can be accessed by looking at the repository that this project forks.
 
 If you have any questions about this project or the program in general, visit [parsity.io](https://parsity.io/) or email hello@parsity.io.
+
+## Requirements
+
+Install dependencies
+
+npm install
+
+Install required packages
+
+npm install react-bootstrap bootstrap axios react-icons
+
+##Database - MongoDB
+
+Create a .env file in your backend directory:
+envPORT=8000
+MONGO_URI=mongodb://localhost/products
+
+OR use your own MongoDB connection string:
+
+MONGO_URI=mongodb+srv://username:password@cluster.mongodb.net/products
+
+## Running the Application
+
+Start the Backend Server
+bash# From root directory
+
+npm run dev
+
+Server will run on http://localhost:8000
+
+Start the Frontend Application
+bash# From frontend directory
+npm run dev
+
+App will run on http://localhost:3000
+
+### Configuration
+
+Port Configuration
+
+Backend: Runs on process.env.PORT || 8000
+Frontend: Must run on port 3000 (CORS is configured for this port)
+
+### Database Configuration
+
+The MongoDB connection string is set to:
+javascriptconst connectString = process.env.MONGO_URI || "mongodb://localhost/products"
+You can either:
+
+Use the default local MongoDB setup
+Set your own MONGO_URI in the .env file
+
+## Troubleshooting
+
+Common Issues:
+CORS Error:
+
+Ensure frontend runs on port 3000
+Check CORS configuration in backend
+
+Database Connection:
+
+Verify MongoDB is running locally
+Check MONGO_URI environment variable
+
+Port Already in Use:
+
+Change PORT in .env file
+
+to see products, go to http://localhost:8000/api/products
