+        Minimum CUDA version to run the software, in X.Y format.  This
+        corresponds to a CUDA SDK release.  When running directly on
+        the host (not in a container) the host must have a compatible
+        CUDA SDK (matching the exact version, or, starting with CUDA
+        11.3, matching major version).  When run in a container, the
+        container image should provide the CUDA runtime, and the host
+        driver is injected into the container.  In this case, because
+        CUDA drivers are backwards compatible, it is possible to
+        use an older SDK with a newer driver across major versions.
