+## Purpose
+This component disables the creation of a default ArgoCD instance in the `openshift-gitops` namespace.
+
+For more information on this option please refer to the following:

+
+## Usage
+
+This component can be added to a base by adding the `components` section to your overlay `kustomization.yaml` file:
+
+```
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+
+resources:
+  - ../../base
+
+components:
+  - ../../components/disable-default-instance
+```
