+Let's deploy these applications using an ApplicationSet as we did previously but this time we will use a git generator. However
+the git generator is somewhat more complex, let's test it locally first.
+
+Output the ApplicationSet to a file replacing the workshop $USER variable with your user:
+
+[.console-input]
+[source,sh,subs="attributes",role=execute]
+----
+sed 's/$USER/user5/' ~/workshop/content/modules/ROOT/examples/applicationsets/coolstore-git-appset.yaml > ~/appset.yaml
+----
+
+Next generate the ApplicationSet locally using the `argocd` CLI:
+
+[.console-input]
+[source,sh,subs="attributes",role=execute]
+----
+argocd appset generate ~/appset.yaml

+Three Applications are being generated, one for each environment.
+
+To see the YAML for each Application run the following:
+
+[.console-input]
+[source,sh,subs="attributes",role=execute]
+----
+argocd appset generate ~/appset.yaml -o yaml
+----
+
+[IMPORTANT]
+Using the CLI to generate Applications is very useful when debugging complex ApplicationSets since
+you do not have to spend the time deploying it to the cluster and looking at the Status block to
+understand why it isn't working.
+
+Now that the generation has been verified, go ahead and deploy it:
