 ## Database Schema
 
+This application uses [DrizzleORM](https://orm.drizzle.team/) which supports multiple database backends:
+- **PostgreSQL** (default, included in Docker container)
+- **MySQL/MariaDB** (connect to external server)
+- **SQLite** (for local development)
+
 Database schemas are defined in `src/models/Schema.ts` using DrizzleORM. To modify the schema:
 
 1. Edit `src/models/Schema.ts`
 2. Generate migration: `npm run db:generate`
 3. Apply migration: `npm run db:migrate`
 
+### Connecting to Different Databases
+
+The included PostgreSQL in Docker is just the default option. You can connect to any database by setting the `DATABASE_URL` environment variable:
+
+**PostgreSQL:**
+```env
+DATABASE_URL=******localhost:5432/mydb
+```
+
+**MySQL:**
+```env
+DATABASE_URL=mysql://user:password@localhost:3306/mydb
+```
+
+**SQLite:**
+```env
+DATABASE_URL=file:./local.db
+```

 ## Authentication
