+
+## Available Examples
+
+### Database Configurations
+- **Database Examples**: [database/README.md](./database/README.md)
+  - **Embedded PostgreSQL**: [database/embedded/values.yaml](./database/embedded/values.yaml)
+  - **External PostgreSQL (Direct Credentials)**: [database/external/direct-credentials.yaml](./database/external/direct-credentials.yaml)
+  - **External PostgreSQL (Existing Secret)**: [database/external/existing-secret.yaml](./database/external/existing-secret.yaml)
+
+### Network Configurations
+- **Network Examples**: [network/README.md](./network/README.md)
+  - **Ingress**: [network/ingress/values.yaml](./network/ingress/values.yaml)
+  - **LoadBalancer**: [network/loadbalancer/values.yaml](./network/loadbalancer/values.yaml)
+
+### Object Storage Configurations
+- **Object Storage Examples**: [object-storage/README.md](./object-storage/README.md)
+  - **Embedded MinIO**: [object-storage/embedded/values.yaml](./object-storage/embedded/values.yaml)
+  - **External S3 (Direct Credentials)**: [object-storage/external/direct-credentials.yaml](./object-storage/external/direct-credentials.yaml)
+  - **External S3 (Existing Secret)**: [object-storage/external/existing-secret.yaml](./object-storage/external/existing-secret.yaml)
+
+## Usage
+
+You can use these example values files as a starting point for your own deployment:
+
+```bash
+helm install mlflow ./charts/mlflow -f ./charts/mlflow/examples/database/embedded/values.yaml
+```
+
+Or combine multiple example files:
+
+```bash
+helm install mlflow ./charts/mlflow \
+  -f ./charts/mlflow/examples/database/embedded/values.yaml \
+  -f ./charts/mlflow/examples/network/ingress/values.yaml
+```
+
+## Customization
+
+These examples provide basic configurations. For production deployments, make sure to:
+
+1. Set secure passwords
+2. Configure proper TLS certificates
+3. Adjust resource requests and limits
+4. Review other settings in the main `values.yaml` file
+
+Refer to the main [README.md](../README.md) for complete configuration options.
