+# Summary
+
+This provide a basic ansible role to deploy the prometheus node exporter. 
+
+Please note, this is not the most flexible role but fits well into my infrastructure. More
+configurations can be added easyly. Get in touch!
+
+## Configuration
+
+In order to use this role, you need to provide the following configuration:
+
+### `node_exporter_domain` 
+
+This is the domain serving the API.
+
+### `node_exporter_cert` 
+
+This specifies which domain should be used for SSL. Useful if you use wildcard
+certs. These are expected to live in `/etc/nginx/certs`.
+
+### `prometheus_pass` 
+
+This specifies the HTTP Basic Auth password to secure the prometheus endpoint.
