            ### Container Images

            Pull the latest release images from GitHub Container Registry:

            ```bash
            # API Server
            docker pull ghcr.io/${{ github.repository }}/kg-api:${{ steps.version.outputs.version_no_v }}

            # Web UI
            docker pull ghcr.io/${{ github.repository }}/kg-web:${{ steps.version.outputs.version_no_v }}

            # Operator
            docker pull ghcr.io/${{ github.repository }}/kg-operator:${{ steps.version.outputs.version_no_v }}
            ```

            Or use `latest` for the most recent stable version:

            ```bash
            docker pull ghcr.io/${{ github.repository }}/kg-api:latest
            docker pull ghcr.io/${{ github.repository }}/kg-web:latest
            docker pull ghcr.io/${{ github.repository }}/kg-operator:latest
            ```

            ### Installation
