+## Resource Discovery
+
+The CLI discovers RunsOn resources using the AWS Resource Groups Tagging API (RGTA):
+
+1. **Primary**: `runs-on-stack-name` tag (all new CF/TF deployments)
+2. **Fallback**: Dynamic discovery via AppRunner service tags (older stacks)
+
+Resources are identified by their `runs-on-resource` tag (Terraform) or ARN pattern matching (fallback):
+
+| Resource | Tag Value | CF Fallback |
+|----------|-----------|-------------|
+| AppRunner Service | `apprunner-service` | ARN pattern |
+| Config S3 Bucket | `config-bucket` | `runs-on/purpose=config` tag or name contains `-config` |
+| EC2 Log Group | `ec2-log-group` | Name contains `{stack}/ec2/instances` |
+
+Tags are automatically applied when deploying RunsOn via Terraform/OpenTofu or CloudFormation.
