+# Database Setup Guide
+
+This guide helps you set up the PostgreSQL database for ASLE backend.
+
+## Prerequisites
+
+- PostgreSQL 15+ installed and running
+- Access to create databases
+
+## Quick Setup
+
+### Option 1: Using Docker (Recommended)
+
+```bash
+# Start PostgreSQL container
+docker-compose up -d postgres
+
+# The database will be created automatically with:
+# - User: asle
+# - Password: asle_password
+# - Database: asle
+```
+
+Update `backend/.env`:
+```env
+DATABASE_URL="postgresql://asle:asle_password@localhost:5432/asle?schema=public"
+```
+
+### Option 2: Local PostgreSQL
+
+1. **Create database:**
+   ```bash
+   # As postgres superuser
+   sudo -u postgres psql -c "CREATE DATABASE asle;"
+   
+   # Or create a user first
+   sudo -u postgres psql -c "CREATE USER asle WITH PASSWORD 'your_password';"
+   sudo -u postgres psql -c "CREATE DATABASE asle OWNER asle;"
+   ```
+
+2. **Update `backend/.env`:**
+   ```env
+   DATABASE_URL="postgresql://asle:your_password@localhost:5432/asle?schema=public"
+   ```
+
+### Option 3: Using Existing PostgreSQL
+
+If you have PostgreSQL running with different credentials:
+
+1. **Create database:**
+   ```bash
+   psql -U your_user -c "CREATE DATABASE asle;"
+   ```
+
+2. **Update `backend/.env`:**
+   ```env
+   DATABASE_URL="postgresql://your_user:your_password@localhost:5432/asle?schema=public"
+   ```
+
+## Running Migrations
+
+After setting up the database:
+
+```bash
+cd backend
+
+# Generate Prisma client
+npm run prisma:generate
+
+# Run migrations
+npm run prisma:migrate
+
+# Initialize database with default configs
+npm run setup:db
+
+# Create admin user
+npm run setup:admin
+```
+
+## Troubleshooting
+
+### Authentication Failed
+
+If you see `Authentication failed`:
+
+1. Check PostgreSQL is running:
+   ```bash
+   pg_isready -h localhost -p 5432
+   ```
+
+2. Verify credentials in `backend/.env`
+
+3. Test connection:
+   ```bash
+   psql $DATABASE_URL -c "SELECT version();"
+   ```
+
+### Database Already Exists
+
+If database already exists, migrations will still work:
+```bash
+npm run prisma:migrate
+```
+
+### Permission Denied
+
+If you get permission errors:
+```bash
+# Grant permissions
+sudo -u postgres psql -c "GRANT ALL PRIVILEGES ON DATABASE asle TO your_user;"
+```
+
+## Connection String Format
+
+```
+postgresql://[user]:[password]@[host]:[port]/[database]?schema=public
+```
+
+Examples:
+- `postgresql://postgres@localhost:5432/asle?schema=public` (no password)
+- `postgresql://asle:password@localhost:5432/asle?schema=public` (with password)
+- `postgresql://user:pass@db.example.com:5432/asle?schema=public` (remote)
+
+## Next Steps
+
+After database is set up:
+1. ✅ Run migrations
+2. ✅ Initialize database
+3. ✅ Create admin user
+4. ✅ Start backend: `npm run dev`
