 =======
 Tools for detecting various kinds of lag.
 
+
+Commands
+--------
+
+```/nerdlag event watch (<plugin> | all) [<thresh_nanos>]```
+ * Start watching the duration of event handlers for the specified plugin, or all plugins.
+ * If an integer argument <thresh_nanos> is given, then event handlers that take longer than that many nanoseconds to execute are reported.
+ * Maximum event durations are reported by `/nerdlag event report` (not yet implemented).  Until that command is implemented, it is advisable to always specify a reporting threshold, since there is no other way to see results.
+
+```/nerdlag event unwatch (<plugin> | all)</li>```
+ * Stop watching the duration of event handlers for the specified plugin, or all plugins.
+
+
+```/nerdlag event subscribe```
+ * Subscribe to in-game notifications of reports of events that exceed their duration threshold.
+ * Reports will always be written to the server log, regardless of whether you subscribe to in-game notifications.
+
+```/nerdlag event unsubscribe```
+ * Unsubscribe from in-game notifications of reports of events that exceed their duration threshold.
+
+
