+# Official Prometheus Exporter Plugin for Discourse
+
+The Discourse Prometheus plugin collects key metrics from Discourse and exposes them in the `/metrics` path so prometheus can consume them.
 
 ## Adding custom global collectors
 
 The global reporter can pick custom metrics added by other Discourse plugins. The metric needs to define a collect method, and the `name`, `labels`, `description`, `value`, and `type` attributes. See an example [here](https://github.com/discourse/discourse-antivirus/pull/15).
