 ## Prerequisites
 
-For this lab it is required to:
+Make sure the following Apps are enabled: 
 
-- Enable `Tempo`
-- Enable `Otel`
-- Enable `Loki`
-- Enable `Grafana`
-- Enable tracing for `Istio` and `Nginx Ingress`
+- `Tempo` on Platform
+- `Otel` on Platform
+- `Loki` on Platform
+- `Grafana` for the Team
+
+Enable tracing for `Istio` and `ingress-nginx-platform`:

+3. Click on the configuration icon
+4. Click on the `Values` tab
