+Configuration
+=============
+
+mod\_prometheus itself doesn’t have any configuration option, but it
+requires Prosody’s [internal statistics
+provider](https://prosody.im/doc/statistics#built-in_providers) to be
+enabled.  You may also want to change the default collection interval
+to the one your statistics consumer is using.
+
+```lua
+statistics = "internal"
+statistics_interval = 15 -- in seconds
+```
+
+See also the documentation of Prosody’s [HTTP
+server](https://prosody.im/doc/http), since Prometheus is an HTTP
+protocol that is how you can customise its URL.  The default one being
+http://localhost:5280/metrics
