+### Default manifests installed by idpbuilder
+
+The default manifests for the core packages are available [here](pkg/controllers/localbuild/resources). 
+These are generated by scripts. If you want to make changes to them, see below.
+
+#### ArgoCD
+
+ArgoCD manifests are generated using a bash script available [here](./hack/argo-cd/generate-manifests.sh). 
+This script runs kustomize to modify the basic installation manifests provided by ArgoCD. Modifications include:
+
+1. Prevent notification and dex pods from running. This is done to keep the number of pods running low by default.
+2. Use the annotation tracking instead of the default label tracking. Annotation tracking allows you to avoid [problems caused by the label tracking method](https://argo-cd.readthedocs.io/en/stable/user-guide/resource_tracking/). In addition, this configuration is required when using Crossplane.
