+## Configuration Management
+
+### ConfigMap Deployment
+
+The Django application uses a ConfigMap for application configuration. The ConfigMap contains environment variables and settings for the Django application.
+
+#### ConfigMap File
+- **File**: `configmap.yaml`
+- **Name**: `django-config`
+- **Namespace**: `vorgabenui`
+- **Version**: 0.990
+
+#### Configuration Contents
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: django-config
+  namespace: vorgabenui
+data:
+  # Django Configuration
+  DEBUG: "false"
+  DJANGO_ALLOWED_HOSTS: "vorgabenportal.knowyoursecurity.com,localhost,127.0.0.1,*"
+  DJANGO_SETTINGS_MODULE: "VorgabenUI.settings"
+  
+  # Application Configuration
+  LANGUAGE_CODE: "de-ch"
+  TIME_ZONE: "UTC"
+  
+  # Static and Media Configuration
+  STATIC_URL: "/static/"
+  MEDIA_URL: "/media/"
+  
+  # Application Version
+  VERSION: "0.990"
+  
+  # Database Configuration (for future use)
+  # DATABASE_ENGINE: "django.db.backends.sqlite3"
+  # DATABASE_NAME: "/app/data/db.sqlite3"
+  
+  # Security Configuration
+  # CSRF_TRUSTED_ORIGINS: "https://vorgabenportal.knowyoursecurity.com"
+```
+
+#### Deployment Script
+The ConfigMap is deployed using the `deploy-argocd-configmap.sh` script located in the `scripts/` directory.
+
+**Script Usage**:
+```bash
+# Deploy ConfigMap
+./scripts/deploy-argocd-configmap.sh
+
+# Verify ConfigMap only (no deployment)
+./scripts/deploy-argocd-configmap.sh --verify-only
+
+# Dry-run (show what would be deployed)
+./scripts/deploy-argocd-configmap.sh --dry-run
+```
+
+**Script Features**:
+- Validates kubectl availability
+- Checks if ConfigMap file exists
+- Creates namespace if it doesn't exist
+- Applies ConfigMap configuration
+- Verifies successful deployment
+- Provides detailed logging and error handling
+
+### Secret Deployment
+
+The Django application requires a secure SECRET_KEY for cryptographic signing. This is managed through a Kubernetes Secret.
+
+#### Secret Configuration
+- **Secret Name**: `vorgabenui-secrets`
+- **Secret Key**: `vorgabenui_secret`
+- **Namespace**: `vorgabenui`
+
+#### Secret Generation
+The secret is automatically generated using the `deploy-argocd-secret.sh` script, which creates a secure Django-style SECRET_KEY.
+
+**Script Usage**:
+```bash
+# Generate and deploy new secret
+./scripts/deploy-argocd-secret.sh
+
+# Verify existing secret only (no new generation)
+./scripts/deploy-argocd-secret.sh --verify-only
+
+# Dry-run (show what would be done)
+./scripts/deploy-argocd-secret.sh --dry-run
+```
+
+**Secret Generation Features**:
+- Generates secure 50-character SECRET_KEY using Python
+- Uses Django-style character set (letters, digits, special characters)
+- Creates or updates the secret in the vorgabenui namespace
+- Verifies secret deployment and accessibility
+- Tests secret accessibility in Django pods
+
+#### Environment Variable Reference
+The deployment.yaml references the secret through environment variables:
+
+```yaml
+env:
+  # Secret configuration
+  - name: VORGABENUI_SECRET
+    valueFrom:
+      secretKeyRef:
+        name: vorgabenui-secrets
+        key: vorgabenui_secret
+```
+
+#### Security Notes
+- The SECRET_KEY is never logged or displayed in full
+- Only the first 10 characters are shown during generation for verification
+- The secret is stored securely in Kubernetes and only accessible to authorized pods
+- Regular secret rotation is recommended for production environments
+
