+**Change podman executable**

+To change the podman executable from the standard podman, export environment variable MOLECULE_PODMAN_EXECUTABLE. For instance if you wish to run molecule with podman-remote instead of ordinary podman, the variable can be exportet as:
+
+export MOLECULE_PODMAN_EXECUTABLE=podman-remote
