+### Specific logical resources
+
+Sometimes you may wish to find an ID or other information from a logical resource
+in a Quilt stack. The following example is for security groups. Modify the commands as needed
+for other resource types.
+
+<!--pytest.mark.skip-->
+```sh
+STACK_NAME="YOUR_QUILT_STACK"
+RESOURCE_ID="YOUR_LOGICAL_ID"
+SG_ID=$(
+  aws cloudformation describe-stack-resource \
+    --stack-name "${YOUR_QUILT_STACK}" \
+    --logical-resource-id "${YOUR_LOGICAL_ID}" \
+    --query 'StackResourceDetail.PhysicalResourceId' \
+    --output text
+)
+aws ec2 describe-security-groups --group-ids "${SG_ID}"
+```
