 ### Deploying to the local cluster
 
 In Argo CD, the 'local cluster' is the cluster upon which Argo CD (and the ApplicationSet controller) is installed. This is to distinguish it from 'remote clusters', which are those that are added to Argo CD [declaratively](https://argoproj.github.io/argo-cd/operator-manual/declarative-setup/#clusters) or via the [Argo CD CLI](https://argoproj.github.io/argo-cd/getting_started/#5-register-a-cluster-to-deploy-apps-to-optional).
