+# contributioncancelactions
+
+![Screenshot](/images/screenshot.png)
+
+This extension cancels memberships, participation records,
+and pledge payments when the related
+contribution is cancelled. If you do not wish them to be cancelled
+then disable the extension. If you want more complex logic
+you may be able to achieve it using civirules or another extension.
+
+This code was part of the core code prior to 5.32 at which point
+it was separated to an optional extension.
+
+The extension is licensed under [AGPL-3.0](LICENSE.txt).
+
+## Requirements
+
+* PHP v7.1+
+* CiviCRM 5.32+
+
+## Installation (Web UI)
+
+This extension ships with core - you can enable or disable in the extensions UI.
