+description: Configure Stirling-PDF using environment variables, settings files, or in-app settings
+---
+
+# Configuration Guide
+
+Stirling-PDF can be configured in three ways, depending on your deployment and preferences.
+
+## Configuration Methods
+
+### 1. In-App Settings (Recommended)
+
+If you have login enabled, admins can configure everything through the Settings menu in the application.
+
+**To use:**
+1. Set `SECURITY_ENABLELOGIN=true`
+2. Log in as admin
+3. Go to Settings → configure through UI
+4. Changes apply immediately, no restart needed
+
+**Best for:** Production deployments with admin users
+
+---
+
+### 2. Environment Variables
+
+Configure via Docker environment variables or system environment variables.
+
+**To use:**
+```bash
+docker run -d \
+  -e SECURITY_ENABLELOGIN=true \
+  -e LANGS=en_GB \
+  stirlingtools/stirling-pdf:latest
+```
+
+**Best for:** Docker deployments, infrastructure-as-code, initial setup
+
+---
+
+### 3. Settings File (settings.yml)
+
+Edit `/configs/settings.yml` directly for advanced configuration.
+
+**To use:**
+```yaml
+security:
+  enableLogin: true
+system:
+  defaultLocale: en-GB
+```
+
+**Best for:** Complex configurations, when you prefer file-based config
+
+---
+
+## Common Settings
+
+### Authentication
+
+Enable user login:
+```bash
+SECURITY_ENABLELOGIN=true
+SECURITY_INITIALLOGIN_USERNAME=admin
+SECURITY_INITIALLOGIN_PASSWORD=changeme123
+```
+
+Default credentials: `admin` / `stirling` (change immediately after first login)
+
+### Language & Localization
+
+```bash
+LANGS=en_GB                    # Available languages
+SYSTEM_DEFAULTLOCALE=en-GB     # Default language
+```
+
+### Deployment Mode
+
+```bash
+MODE=BOTH      # Options: BOTH, FRONTEND, BACKEND
+```
+
+### File Upload Limits
+
+```bash
+SYSTEM_MAXFILESIZE=2000        # MB
+SPRING_SERVLET_MULTIPART_MAX_FILE_SIZE=2000MB
+SPRING_SERVLET_MULTIPART_MAX_REQUEST_SIZE=2000MB
+```
+
+### Memory Management
+
+```bash
+JAVA_TOOL_OPTIONS="-Xms512m -Xmx4g"  # Min 512MB, Max 4GB RAM
+```
+
+---
+
+## Specialized Configuration Guides
+
+For advanced features and specific use cases, see these detailed guides:
+
+### Authentication & Security
+
+**[Single Sign-On (SSO)](./Single%20Sign-On%20Configuration.md)**
+- OAuth2 (Google, GitHub, Keycloak, OIDC)
+- SAML2 (Okta, Azure AD) - Pro/Enterprise only
+- Complete configuration examples
+
+**[System and Security](./System%20and%20Security.md)**
+- Split deployment (frontend/backend separation)
+- CORS configuration
+- Server certificates
+- JWT configuration
+
+**[Fail2Ban Integration](./Fail2Ban.md)**
+- Protect against brute-force attacks
+- Auto-ban after failed login attempts
+
+---
+
+### Features & Customization
+
+**[UI Customization](./UI%20Customisation.md)**
+- Branding and logos
+- Theme customization
+- Custom styling
+
+**[Endpoint/Feature Control](./Endpoint%20or%20Feature%20Customisation.md)**
+- Enable/disable specific tools
+- Control feature availability by user/role
+
+**[Pipeline (Automation)](./Pipeline.md)**
+- Automated workflows
+- Folder scanning
+- Batch processing
+- Multi-step operations
+
+---
+
+### Integration & Storage
+
+**[External Database](./External%20Database.md)**
+- PostgreSQL configuration (Pro/Enterprise)
+- Database migration
+- Backup strategies
+
+**[Google Drive File Picker](./Google%20Drive%20File%20Picker.md)**
+- Direct Google Drive integration
+- OAuth setup
+
+**[OCR Configuration](./OCR.md)**
+- Tesseract language packs
+- OCR optimization
+
+**[Usage Monitoring](./Usage%20Monitoring.md)**
+- Prometheus metrics (Pro/Enterprise)
+- Application monitoring
+- Performance tracking
+
+---
+
+### Other Configuration
+
+**[Folder Scanning](./FolderScanning.md)**
+- Watch folders for automatic processing
+
+**[Custom Signature Files](./Sign%20with%20custom%20files.md)**
+- Pre-loaded signatures for quick signing
+
+**[Extra Settings](./Extra-Settings.md)**
+- Logging configuration
+- Server settings (port, SSL/TLS)
+- Advanced Spring Boot settings
+
+---
+
+## Configuration Priority
+
+When the same setting is defined in multiple places, this is the order of precedence (highest to lowest):
+
+1. **Environment Variables**
+2. **settings.yml / In-App Settings**
+3. **Default values**
+
+---
+
+## Environment Variable Format
+
+Convert YAML paths to environment variables:
+
+```yaml
+# settings.yml
+security:
+  enableLogin: true
+```
+
+Becomes:
+```bash
+SECURITY_ENABLELOGIN=true
+```
+
+**Rules:**
+- Uppercase everything
+- Replace `.` with `_`
+- Nested properties become `PARENT_CHILD`
+
+---
+
+## Troubleshooting
+
+### Settings Not Applied
+
+1. Check configuration priority (env vars override settings.yml)
+2. Restart container after changing environment variables
+3. Check logs: `docker logs stirling-pdf | grep ERROR`
+4. Verify file permissions on `/configs` volume
+
+### Database Issues
+
+Default database location: `/configs/stirling-pdf-DB.mv.db`
+
+If missing:
+- Ensure `/configs` volume is mounted
+- Check write permissions
+- Review startup logs
+
+---
+
+## Next Steps

+- **Production Deployment:** See [Production Deployment Guide](../Server-Admin-Onboarding.md)
+- **API Usage:** See [API Documentation](../API.md)
+- **Tool Reference:** See [Functionality](../Functionality/Functionality.md)
