 # Install Kepler as RPM
 
+## Versions 0.7.10 and newer
+The current rpm release is a systemd unit that starts a podman container.
+
+Download the latest stable release from the Kepler release URL [download](https://github.com/sustainable-computing-io/kepler/releases/)
+
+```sh
+tar xvzf kepler.rpm.tar.gz
+yum install RPMS/noarch/container-kepler-0.7.10-1.noarch.rpm
+systemctl enable container-kepler --now
+```
+
+Verify that podman starts a kepler container via
+
+`sudo podman ps`
+
+then via your browser pointing to the URL below on the preconfigured port [browser](http://localhost:8888/metrics)
+
+or via a curl command:
+
+`curl localhost:8888/metrics | grep kepler_node_package_joules_total`
+
+
+## Versions prior to 0.7.10
+Older version directly install kepler as a rpm package (as opposed to as a container in newer versions)
 To install the Kepler RPM [download](https://github.com/sustainable-computing-io/kepler/releases/) the latest stable version, unpack and install:
