+# Docker Setup Guide (Linux)
+
+Since you're using Docker for the database, here's the correct setup process:
+
+## Prerequisites
+
+- **Node.js** (v16+): `sudo apt install nodejs npm` or use NodeSource
+- **Docker**: `sudo apt install docker.io docker-compose-plugin`
+- **Docker Compose**: Included with modern Docker installations
+
+## Step 1: Start the Database with Docker
+
+```bash
+cd backend
+
+# Start PostgreSQL in Docker
+docker compose up -d
+
+# Verify the database is running
+docker compose ps
+
+# You should see:
+# bookmark_postgres   postgres:15   Up   0.0.0.0:5432->5432/tcp
+```
+
+## Step 2: Backend Setup
+
+```bash
+# Install Node.js dependencies
+npm install
+
+# Copy environment file
+cp .env.example .env
+```
+
+## Step 3: Configure Environment for Docker Database
+
+Edit `backend/.env` with these Docker-specific settings:
+
+```env
+# Server Configuration
+NODE_ENV=development
+PORT=3001
+
+# Database Configuration (Docker settings)
+DB_HOST=localhost
+DB_PORT=5432
+DB_NAME=bookmark_manager
+DB_USER=postgres
+DB_PASSWORD=password
+DB_SSL=false
+
+# JWT Configuration (CHANGE THIS)
+JWT_SECRET=your_very_long_random_secret_key_at_least_32_characters_long
+JWT_EXPIRES_IN=24h
+
+# Email Configuration (OPTIONAL for now)
+EMAIL_HOST=smtp.gmail.com
+EMAIL_PORT=587
+EMAIL_SECURE=false
+EMAIL_USER=
+EMAIL_PASSWORD=
+EMAIL_FROM=
+
+# Application Configuration
+ALLOWED_ORIGINS=http://localhost:3000,http://127.0.0.1:3000
+BASE_URL=http://localhost:3001
+
+# Security Configuration
+BCRYPT_SALT_ROUNDS=12
+RATE_LIMIT_WINDOW_MS=900000
+RATE_LIMIT_MAX_REQUESTS=100
+AUTH_RATE_LIMIT_MAX=5
+```
+
+## Step 4: Create Test Database
+
+```bash
+# Connect to the Docker PostgreSQL instance
+docker exec -it bookmark_postgres psql -U postgres -d bookmark_manager
+
+# Create the test database
+CREATE DATABASE bookmark_manager_test;
+
+# Exit PostgreSQL
+\q
+```
+
+## Step 5: Initialize Database Tables
+
+```bash
+# Initialize the database schema
+npm run db:init
+
+# Check database status
+npm run db:status
+```
+
+## Step 6: Start the Application
+
+```bash
+# Start the backend server
+npm run dev
+
+# You should see:
+# Server running on port 3001
+# Database connected successfully
+```
+
+## Step 7: Access the Application
+
+Open your browser to: `http://localhost:3001`
+
+The backend now serves the frontend static files automatically - no need for a separate web server!
+
+## Useful Docker Commands
+
+```bash
+# Start the database
+docker compose up -d
+
+# Stop the database
+docker compose down
+
+# View database logs
+docker compose logs postgres
+
+# Connect to database directly
+docker exec -it bookmark_postgres psql -U postgres -d bookmark_manager
+
+# Reset database (removes all data)
+docker compose down -v
+docker compose up -d
+npm run db:init
+```
+
+## Complete Setup Script for Docker
+
+Here's a one-liner setup for Docker:
+
+```bash
+cd backend && \
+docker compose up -d && \
+npm install && \
+cp .env.example .env && \
+echo "Edit .env file now, then run: npm run db:init && npm run dev"
+```
+
+## Troubleshooting Docker Setup
+
+### Docker not running
+```bash
+# Start Docker service
+sudo systemctl start docker
+sudo systemctl enable docker
+
+# Add your user to docker group (logout/login required)
+sudo usermod -aG docker $USER
+```
+
+### Port 5432 already in use
+```bash
+# Check what's using port 5432
+sudo lsof -i :5432
+
+# If it's another PostgreSQL instance, stop it
+sudo systemctl stop postgresql
+
+# Or change the port in docker-compose.yml
+```
+
+### Database connection fails
+```bash
+# Check if container is running
+docker ps | grep postgres
+
+# Check container logs
+docker logs bookmark_postgres
+
+# Test connection
+docker exec -it bookmark_postgres psql -U postgres -c "SELECT version();"
+```
+
+### Permission issues
+```bash
+# Fix Docker permissions
+sudo chmod 666 /var/run/docker.sock
+
+# Or add user to docker group
+sudo usermod -aG docker $USER
+# Then logout and login again
+```
+
+## Environment File for Docker
+
+Here's a ready-to-use `.env` file for the Docker setup:
+
+```env
+NODE_ENV=development
+PORT=3001
+
+# Docker PostgreSQL settings (match docker-compose.yml)
+DB_HOST=localhost
+DB_PORT=5432
+DB_NAME=bookmark_manager
+DB_USER=postgres
+DB_PASSWORD=password
+DB_SSL=false
+
+# Generate a secure JWT secret
+JWT_SECRET=bookmark_manager_super_secret_jwt_key_change_this_in_production_2024
+JWT_EXPIRES_IN=24h
+
+# Email settings (optional)
+EMAIL_HOST=smtp.gmail.com
+EMAIL_PORT=587
+EMAIL_SECURE=false
+EMAIL_USER=
+EMAIL_PASSWORD=
+EMAIL_FROM=
+
+ALLOWED_ORIGINS=http://localhost:3000,http://127.0.0.1:3000
+BASE_URL=http://localhost:3001
+BCRYPT_SALT_ROUNDS=12
+RATE_LIMIT_WINDOW_MS=900000
+RATE_LIMIT_MAX_REQUESTS=100
+AUTH_RATE_LIMIT_MAX=5
+```
+
+This should work perfectly with your Docker setup! Let me know if you encounter any issues.

+# Database connected successfully
+```
+
+## Step 9: Test the Application
+
+1. Open your browser to: `http://localhost:3001`
+2. You should see the bookmark manager interface
+3. Try registering a new account
+
+## Troubleshooting Common Issues
+
+### "npm install" fails
+```bash
+# Clear npm cache
+npm cache clean --force
+
+# Delete node_modules and try again
+rm -rf node_modules package-lock.json
+npm install
+
+# If still fails, try with legacy peer deps
+npm install --legacy-peer-deps
+```
+
+### "Database connection failed"
+```bash
+# Check if PostgreSQL is running
+sudo systemctl status postgresql  # Linux
+brew services list | grep postgresql  # macOS
+
+# Test connection manually
+psql -h localhost -U postgres
+
+# Check your .env file values match your PostgreSQL setup
+```
+
+### "Database does not exist"
+```bash
+# Connect to PostgreSQL and create databases
+sudo -u postgres psql
+CREATE DATABASE bookmark_manager;
+CREATE DATABASE bookmark_manager_test;
+\q
+```
+
+### "Authentication failed for user"
+```bash
+# Reset PostgreSQL password
+sudo -u postgres psql
+ALTER USER postgres PASSWORD 'newpassword';
+\q
+
+# Update your .env file with the new password
+```
+
+### "Port already in use"
+```bash
+# Find what's using the port
+lsof -i :3001
+
+# Kill the process
+kill -9 <PID>

+# Or change the port in .env
+PORT=3002
+```
+
+### "Permission denied"
+```bash
+# Make sure you have write permissions
+chmod 755 backend/
+chmod 644 backend/.env
+```
+
+## Minimal Test Without Database
+
+If you're still having database issues, you can test if the basic setup works:
+
+```bash
+cd backend
+
+# Create a simple test file
+echo "console.log('Node.js works!'); console.log('Dependencies:', Object.keys(require('./package.json').dependencies));" > test.js
+
+# Run it
+node test.js
+
+# Clean up
+rm test.js
+```
+
+## Get Specific Help
+
+**If you're still having issues, please share:**
+
+1. Your operating system
+2. The exact command you ran
+3. The complete error message
+4. Output of these commands:
+   ```bash
+   node --version

+# Bookmark Manager Application
+
+A full-stack bookmark management application with user authentication, built with Node.js/Express backend and vanilla JavaScript frontend.
+
+## Features
+
+- **User Authentication**: Registration, login, email verification, password reset
+- **Bookmark Management**: Create, read, update, delete bookmarks with folders
+- **Security**: JWT authentication, password hashing, SQL injection prevention, XSS protection
+- **Data Import/Export**: Import from browser bookmarks, export to JSON
+- **Search & Filter**: Search bookmarks by title/URL, filter by folder/status
+- **Responsive Design**: Works on desktop and mobile devices
+
+## Prerequisites
+
+- Node.js (v16 or higher)
+- PostgreSQL (v12 or higher)
+- npm or yarn package manager
+
+## Quick Start
+
+### 1. Database Setup
+
+First, create a PostgreSQL database:
+
+```bash
+# Connect to PostgreSQL
+psql -U postgres
+
+# Create database
+CREATE DATABASE bookmark_manager;
+CREATE DATABASE bookmark_manager_test; -- For testing
+
+# Create user (optional)
+CREATE USER bookmark_user WITH PASSWORD 'your_password';
+GRANT ALL PRIVILEGES ON DATABASE bookmark_manager TO bookmark_user;
+GRANT ALL PRIVILEGES ON DATABASE bookmark_manager_test TO bookmark_user;
+```
+
+### 2. Backend Setup
+
+```bash
+# Navigate to backend directory
+cd backend
+
+# Install dependencies
+npm install
+
+# Copy environment file
+cp .env.example .env
+
+# Edit .env file with your database credentials
+nano .env
+```
+
+Configure your `.env` file:
+```env
+# Database Configuration
+DB_HOST=localhost
+DB_PORT=5432
+DB_NAME=bookmark_manager
+DB_USER=postgres
+DB_PASSWORD=your_password
+
+# JWT Configuration
+JWT_SECRET=your-super-secret-jwt-key-change-this-in-production
+JWT_EXPIRES_IN=24h
+
+# Email Configuration (for verification emails)
+EMAIL_HOST=smtp.gmail.com
+EMAIL_PORT=587
+EMAIL_USER=your-email@gmail.com
+EMAIL_PASS=your-app-password
+
+# Server Configuration
+PORT=3000
+NODE_ENV=development
+```
+
+### 3. Initialize Database
+
+```bash
+# Initialize database tables
+npm run db:init
+
+# Check database status
+npm run db:status
+```
+
+### 4. Start the Backend Server
+
+```bash
+# Development mode (with auto-reload)
+npm run dev
+
+# Or production mode
+npm start
+```
+
+The backend server will start on `http://localhost:3000`
+
+### 5. Access the Application
+
+The backend now serves the frontend static files automatically:
+
+- Start the backend server: `npm run dev` (from the backend directory)
+- Open your browser to: `http://localhost:3001`
+- The frontend files (HTML, CSS, JS) are served directly by the backend
+
+**Alternative: Use a separate web server (optional)**
+```bash
+# From the root directory, serve with any static server
+npx http-server -p 8080
+# Then open http://localhost:8080
+# Note: You'll need to update API URLs in the frontend to point to localhost:3001
+```
+
+## Running Tests
+
+The application includes a comprehensive test suite with unit tests, integration tests, and security tests.
+
+### Test Setup
+
+```bash
+cd backend
+
+# Make sure test database exists
+psql -U postgres -c "CREATE DATABASE bookmark_manager_test;"
+
+# Run all tests
+npm test
+
+# Run specific test types
+npm run test:unit        # Unit tests only
+npm run test:integration # Integration tests only
+npm run test:security    # Security tests only
+
+# Run tests with coverage report
+npm run test:coverage
+
+# Run tests in watch mode (for development)
+npm run test:watch
+```
+
+### Test Database
+
+The tests use a separate test database (`bookmark_manager_test`) to avoid affecting your development data. The test suite automatically:
+- Sets up test database tables
+- Runs tests in isolation
+- Cleans up test data after each test

+```bash
+# Check Node.js version (should be 16+)
+node --version
+
+# Check npm version
+npm --version
+
+# Check if PostgreSQL is installed and running
+psql --version
+
+# Check if PostgreSQL service is running
+# On Ubuntu/Debian:
+sudo systemctl status postgresql
+
+# On macOS:
+brew services list | grep postgresql
+
+# On Windows:
+# Check Services in Task Manager for PostgreSQL
+```
+
+### Step 2: Database Setup (Most Common Issue)
+
+```bash
+# Start PostgreSQL if not running
+# Ubuntu/Debian:
+sudo systemctl start postgresql
+
+# macOS:
+brew services start postgresql
+
+# Connect to PostgreSQL (try different approaches)
+# Option 1: Default postgres user
+sudo -u postgres psql
+
+# Option 2: Your system user
+psql -U postgres
+
+# Option 3: Specify host
+psql -h localhost -U postgres
+
+# Once connected, create databases:
+CREATE DATABASE bookmark_manager;
+CREATE DATABASE bookmark_manager_test;
+
+# Create a user (optional but recommended)
+CREATE USER bookmark_user WITH PASSWORD 'secure_password_123';
+GRANT ALL PRIVILEGES ON DATABASE bookmark_manager TO bookmark_user;
+GRANT ALL PRIVILEGES ON DATABASE bookmark_manager_test TO bookmark_user;
+
+# List databases to verify
+\l
+
+# Exit PostgreSQL
+\q
+```
+
+### Step 3: Backend Setup
+
+```bash
+# Navigate to backend directory
+cd backend
+
+# Install dependencies (this might take a while)
+npm install
+
+# If npm install fails, try:
+npm install --legacy-peer-deps
+
+# Or clear cache first:
+npm cache clean --force
+npm install
+```
+
+### Step 4: Environment Configuration
+
+```bash
+# Copy the example environment file
+cp .env.example .env
+
