+#### flags
+The following 5 flags are the most commonly used to control cert-exporter behavior.  They allow you to use file globs to include and exclude certs and kubeconfig files.  
+
+```
+  -exclude-cert-glob value
+    	File globs to exclude when looking for certs.
+  -exclude-kubeconfig-glob value
+    	File globs to exclude when looking for kubeconfigs.
+  -include-cert-glob value
+    	File globs to include when looking for certs.
+  -include-kubeconfig-glob value
+    	File globs to include when looking for kubeconfigs.
+  -polling-period duration
+    	Periodic interval in which to check certs. (default 1h0m0s)
+```
+
+For a full flag listing run the application with the `--help` parameter.

 ### Usage
 
-wip
+cert-exporter supports x509 certificates on disk encoded in the [PEM format](https://en.wikipedia.org/wiki/Privacy-Enhanced_Mail) as well as certs embedded or referenced from kubeconfig files.  Certificates are often stored both ways when building clusters.
+
+See [deployment](./docs/deploy.md) for detailed information on running cert-exporter and examples of running it in a [kops](https://github.com/kubernetes/kops) cluster.
+
+### Dashboard
+
+After running cert-exporter in your cluster it's easy to build a [custom dashboard](./docs/sample-dashboard.yaml) to expose information about the certs in your cluster.
