+%description
+The Prometheus Pushgateway exists to allow ephemeral and batch jobs to expose their metrics to Prometheus.
+Since these kinds of jobs may not exist long enough to be scraped, they can instead push their metrics to a Pushgateway.
+The Pushgateway then exposes these metrics to Prometheus.
