+# Alert Rules
+
+Alert rules are configurations that define conditions, scope, and actions for generating alerts from
+monitored signals, such as metrics, logs, or activity. When an alert rule's defined conditions are
+met for a specific resource within its scope, the system generates a triggered alert, which is the
+actual instance of the condition being met. These rules specify the data to monitor, the trigger
+threshold, and the resulting actions, like sending notifications to specific receivers or performing
+automated tasks.
