 Before proceeding to any kind of test, you'll first have to deploy your custom branch app's version into a testing installation. Don't forget to suspend flux reconciliation for this app during the whole testing process. See [here](https://intranet.giantswarm.io/docs/dev-and-releng/flux/suspending-flux/#how-to-be-more-granular--subtle-with-suspending-resources-and-why-be-careful-with-this) for details on how to evict an app from flux's reconciliation.
 
-Obviously you'll have to check that the deployment of your custom branch's version has gone smoothly. If the app is in a different state than `deployed` please describe the app and try to fix it according to the displayed events' description.
+Once that's done, please run the `basic_checks.sh` script which will check that the app is in `deployed` state and that the `loki-canary` component is enabled.
 
-Once your app is correctly deployed,  :
+Once your app is correctly deployed and configured :
 
 - Let it run for a bit, like 10min or more.
-- Make sure that the `loki-canary` component is enabled and deployed. If not, please create a user values configmap on the installation to enable the canary.
 - Inspect the `Loki / Operational` dasboard which will give information on Loki's overall health.
 - If everything appears to be fine, then you can revert the flux's evicting procedure that you did and let it reconcile to its original version.
