+## Known Limitations
+
+Since this module is experimental, there are some known limitations:
+
+- Currently this module does not support CDK Pipelines. You must deploy CDK Apps using this 
+  synthesizer via `cdk deploy`.
+- This synthesizer only needs a bootstrap stack with Roles, without staging resources. We
+  haven't written such a bootstrap stack yet; at the moment you can use the existing modern
+  bootstrap stack, the staging resources in them will just go unused.
+- Due to limitations on the CloudFormation template size, CDK Applications can have
+  at most 38 independent ECR images.
+- When you run `cdk destroy` (for example during testing), the staging bucket and ECR
+  repositories will be left behind because CloudFormation cannot clean up non-empty resources.
+  You must deploy those resources manually if you want to redeploy again using the same `appId`.
