+## Limitations
+
+* The pull request auto remediation feature is only available for rule types that support it.
+* There's no support for creating pull requests that modify the content of existing files yet.
+* The created pull request should be closed manually if the issue is resolved through other means. The profile status and any related alerts will be updated/closed automatically though.
