 ## Configuration

 The drop events transformation uses filters to target specific events for removal.
 
 ### Filtering options
 
 1. **Event matching**: Target specific event types by name (e.g., `$pageview`, `user_signed_up`)

-## Important considerations
+## FAQ
+
+### Is the source code for this transformation available?
+
+PostHog is open-source and so are all the transformations on the platform. The [source code](https://github.com/PostHog/posthog/blob/master/posthog/cdp/templates/drop_events/template_drop_events.py) is available on GitHub.
+
+### What happens to dropped events?
+
+Dropped events are permanently deleted and cannot be recovered. They are removed before ingestion, so they won't appear in any analytics, cohorts, or exports.
+
+### How do I monitor what's being dropped?
+
+Check the metrics and logs tabs regularly to ensure the transformation is working as expected. The metrics tab shows how many events have been processed and dropped.
 
-- **Permanence**: Dropped events are permanently deleted and cannot be recovered
-- **Monitoring**: Check the metrics and logs tabs regularly to ensure the transformation is working as expected
