            ## Multi-Arch Docker Images

            Images are available for Python 3.10, 3.11, 3.12, 3.13, and 3.14 on both AMD64 and ARM64 architectures.

            ### Usage

            Pull a specific Python version:
            ```bash
            docker pull ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ github.ref_name }}-python3.14
            ```

            The images support both AMD64 and ARM64 architectures automatically.

            ### Available Tags
            - `${{ github.ref_name }}-python3.10` (multi-arch)
            - `${{ github.ref_name }}-python3.11` (multi-arch)
            - `${{ github.ref_name }}-python3.12` (multi-arch)
