 !!! warning
     This deployment is currently in alpha stage. Expect breaking changes.
 
+## AWS Resource Cleanup
+
+The Fargate deployment creates several AWS resources that persist even after your deployment stops. These resources include:
+
+- ECS Clusters
+- Task Definitions 
+- Security Groups
+- IAM Roles
+
+All resources created by the Fargate deployment are tagged with `origin=swe-rex-deployment-auto` for tracking purposes.
+
+### Cleaning Up Resources
+
+To clean up all AWS resources created by the Fargate deployment, you can use the built-in teardown utility:
+
+```bash
+python -m swerex.utils.aws_teardown
+```
+
+This utility will:
+
+1. Preview all resources tagged with `origin=swe-rex-deployment-auto`
+2. Request confirmation before deletion
+3. Delete resources in the correct order to handle dependencies
+4. Provide status updates during the cleanup process
+
+!!! tip
+    It's recommended to run the teardown utility periodically to avoid accumulating unused AWS resources, which may incur costs.
+    Running the fargate deployment again will recreate the necessary resources on the fly.
