-> The APIs of higher level constructs in this module are experimental and under active development.
-> They are subject to non-backward compatible changes or removal in any future version. These are
-> not subject to the [Semantic Versioning](https://semver.org/) model and breaking changes will be
-> announced in the release notes. This means that while you may use them, you may need to update
-> your source code when upgrading to a newer version of this package.
+ > This API may emit warnings. Backward compatibility is not guaranteed.
 
-If using monocdk, use [@monocdk-experiment/assert](https://www.npmjs.com/package/@monocdk-experiment/assert) instead.
+## Replacement recommended
+
+This library has been deprecated. We recommend you use the
+[@aws-cdk/assertions](https://docs.aws.amazon.com/cdk/api/v1/docs/assertions-readme.html) module instead.
