+
+| Layer    | Technology                            |
+| -------- | ------------------------------------- |
+| Frontend | React 18, Vite, TailwindCSS, Recharts |
+| Backend  | Node.js, Express 4, mysql2            |
+| Database | MySQL 8.0                             |
+| Auth     | JWT (jsonwebtoken) + bcryptjs         |
+| Forms    | react-hook-form + Zod validation      |

+
+---
+
+## 📋 Prerequisites
+
+- **Node.js** v18 or higher
+- **npm** v9 or higher
+- **MySQL 8.0** running locally
+
+---
+
+## 🚀 Installation & Setup
+
+### 1. Clone the repository
+
+```bash
+git clone "https://github.com/Coding-Moves/BSAI-Projects.git"
+cd msms
+```
+
+### 2. Install all dependencies
+
+```bash
+npm run install:all
+```
+
+This installs root, backend, and frontend packages in one command.
+
+### 3. Configure backend environment
+
+```bash
+cd backend
+cp .env.example .env
+```
+
+Open `.env` and fill in your MySQL credentials:
+
+```
+DB_HOST=localhost
+DB_PORT=3306
+DB_USER=root
+DB_PASSWORD=your_mysql_password
+DB_NAME=msms_db
+JWT_SECRET=change_this_to_a_random_secret
+PORT=5000
+```
+
+### 4. Set up the MySQL database
+
+Open **MySQL Workbench** (or any MySQL client) and run the SQL files **in this exact order**:
+
+```sql
+-- Step 1: Create tables
+SOURCE /path/to/msms/database/schema.sql;
+
+-- Step 2: Insert sample data
+SOURCE /path/to/msms/database/sample_data.sql;
+
+-- Step 3: Create triggers
+SOURCE /path/to/msms/database/triggers.sql;
+
+-- Step 4: Create stored procedures
+SOURCE /path/to/msms/database/stored_procedures.sql;
+
+-- Step 5: Create views
+SOURCE /path/to/msms/database/views.sql;
+
+-- Step 6: Create indexes
+SOURCE /path/to/msms/database/indexes.sql;
+```
+
+Or run them from the command line:
+
+```bash
+mysql -u root -p < database/schema.sql
+mysql -u root -p msms_db < database/sample_data.sql
+mysql -u root -p msms_db < database/triggers.sql
+mysql -u root -p msms_db < database/stored_procedures.sql
+mysql -u root -p msms_db < database/views.sql
+mysql -u root -p msms_db < database/indexes.sql
+```
+
+### 5. Start the application
+
+```bash
+cd ..
+npm run dev
+```
+
+This runs both frontend and backend concurrently:
+
+- **Backend API:** http://localhost:5000
+- **Frontend:** http://localhost:5173
