-Alert processing rules allow you to apply processing on fired alerts. Alert processing rules are different from alert rules. Alert rules generate new alerts, while alert processing rules modify the fired alerts as they're being fired. You can use alert rules to e.g. send an email to the administrator for metric-based changes. You can read further in [action groups](./action-groups.md).
+Alert processing rules allow you to apply processing on fired alerts. Alert processing rules are different from alert rules. Alert rules generate new alerts and notify stakeholders (see [action groups](./action-groups.md)), while alert processing rules modify the fired alerts as they're being fired. 
 
 You can use alert processing rules to add [action groups](./action-groups.md) or remove (suppress) action groups from your fired alerts. You can apply alert processing rules to different resource scopes, from a single resource, or to an entire subscription, as long as they are within the same subscription as the alert processing rule. You can also use them to apply various filters or have the rule work on a predefined schedule.
