 - **For repeated information**: If you need the same data to appear multiple times, create unique placeholders like `{project_name_header}` and `{project_name_footer}` and provide the same value for both
 
+## Storage & Persistence
+
+Templates are stored in two locations for persistence in Docker environments:
+
+### Database Storage
+- **Location**: `data/database.sqlite` (table: `docx_templates`)
+- **Content**: Template metadata (name, description, file paths, timestamps)
+- **Persistence**: Handled by Docker volume mount `./data:/app/data`
+
+### File Storage
+- **Location**: `templates/` (host) → `/app/templates/` (container)
+- **Content**: Actual DOCX template files
+- **Persistence**: Handled by Docker volume mount `./templates:/app/templates`
+- **Web Access**: Files are served via `/api/templates/download/{filename}`
+
+### Docker Volume Mounts
+Both development and production Docker setups include volume mounts to ensure template persistence across container restarts:
+
+```yaml
+volumes:
+  - ./data:/app/data                    # Database
+  - ./templates:/app/templates          # Template files
+  - ./uploads:/app/public/uploads       # Other uploads
+  - ./backups:/app/backups              # Backup files
+```
+
 ## Troubleshooting
 
 - **Duplicate tags error**: Each placeholder can only be used once in the template. If you need the same information to appear multiple times, use unique placeholders like `{project_name_1}` and `{project_name_2}` with the same data value.
