+# Introduction
+
+This module provides a streaming interface to [Prosodys internal statistics][doc:statistics] via
+[Server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events).
+
+## Example
+
+```js
+var evtSource = new EventSource("/stats_stream");
+
+/*
+ * An event with all current statistics in the form of a JSON object.
+ * Normally sent only once, when first connected to the stream.
+ */
+evtSource.addEventListener("stats-full", function(e) {
+	var initial_stats = JSON.parse(e.data);
+	console.log(initial_stats);
+}, false);
+
+/*
+ * An event containing only statistics that have changed since the last
+ * 'stats-full' or 'stats-updated' event.
+ */
+evtSource.addEventListener("stats-updated", function(e) {
+	var updated_stats = JSON.parse(e.data);
+	console.log(updated_stats);
+}, false);
+```
