 - Update and use `build-image-quay-dev.sh` to build a new image with your local changes
 - Reference that new image in `k8s-addition.yaml` and copy to your instance
-- `kubectl apply -f k8s-addition.yaml` will add the `shop-dc-shim-db`, `shop-dc-shim`, and `shop-dc-load-generator` pods to your cluster
+- On your instances with the cluser `export APPDYNAMICS_AGENT_ACCOUNT_ACCESS_KEY=<SE-LABS-TOKEN>`
+- `envsubst < k8s-additions.yaml | kubectl apply -f -` will add the `shop-dc-shim-db`, `shop-dc-shim`, and `shop-dc-load-generator` pods to your cluster
+    - **NOTE:** `envsubst` is important here to pass the appd agent token
 - Once `shop-dc-shim` finishes spinning up (5-7min) the load generator will start sending traffic
