+# Database Import
+
+Place your database backup files here for automatic import during deployment.
+
+## Supported Files
+- `.sql` files (uncompressed SQL dumps)
+- `.sql.gz` files (gzip compressed SQL dumps)
+
+## How to Use
+
+1. **Copy your backup files here:**
+   ```bash
+   cp my_auth_backup.sql.gz ./database-import/
+   cp my_world_backup.sql.gz ./database-import/
+   cp my_characters_backup.sql.gz ./database-import/
+   ```
+
+2. **Run deployment:**
+   ```bash
+   ./deploy.sh
+   ```
+
+3. **Files are automatically copied to backup system** and imported during deployment
+
+## File Naming
+- Any filename works - the system will auto-detect database type by content
+- Recommended naming: `auth.sql.gz`, `world.sql.gz`, `characters.sql.gz`
+
+## What Happens
+- Files from this folder are copied to `local-storage/backups/daily/`
+- Database import system automatically restores them
+- Original files remain here for reference
+
+## Notes
+- Only processed on first deployment (when databases don't exist)
+- Files are copied with timestamp to backup directory
+- Empty folder is ignored - no files, no import
