+# Port testing Addon
+Very simple go webserver that executes an HTTP GET against a
+provided endpoint and tests for an expected returned status code
+
+This application doesn't do any testing itself, it will only execute
+what you want it to. An expected use is to config a dashboard like grafana
+to poll endpoints and check the response.
+
+## Example
+
+```shell script
+curl "http://HOST/?endpoint=https://rancher.lqd.dk&expectedStatusCode=200"
+```
