 # Cluster API Add-on Provider for Cdk8s
 
-## ✨ What is Cluster API Add-on Provider for Cdk8s?
-
-Cluster API Add-on Provider for Cdk8s extends Cluster API by managing the installation, configuration, upgrade, and deletion of cluster add-ons using cdk8s applications. This provider is based on the [Cluster API Add-on Orchestration Proposal](https://github.com/kubernetes-sigs/cluster-api/blob/main/docs/proposals/20220712-cluster-api-addon-orchestration.md), a larger effort to bring orchestration for add-ons to CAPI by using existing package management tools.
-
-This project is a concrete implementation of a ClusterAddonProvider, a pluggable component to be deployed on the Management Cluster. An add-on provider component acts as a broker between Cluster API and a package management tool (in this case, cdk8s).
-
-The aims of the ClusterAddonProvider project are as follows:
-
-#### Goals
-
-- Design a solution for orchestrating Cluster add-ons.
-- Leverage the capabilities of cdk8s for defining and synthesizing Kubernetes manifests.
-- Make add-on management in Cluster API modular and pluggable.
-- Make it clear for developers how to build a Cluster API Add-on Provider based on cdk8s or other tools.
-
-#### Non-goals
-
-- Implement a new, full-fledged package management tool in Cluster API.
-- Provide a mechanism for altering, customizing, or dealing with single Kubernetes resources defining a Cluster add-on, i.e. Deployments, Services, ServiceAccounts. Cluster API should treat add-ons as opaque components and delegate all the operations impacting add-on internals to cdk8s.
-- Expect users to use a specific package management tool (though this provider focuses on cdk8s).
-- Implement a solution for installing add-ons on the management cluster itself.

 ## Cdk8sAppProxy CRD
 
 The `Cdk8sAppProxy` CustomResourceDefinition (CRD) is used to manage the deployment of cdk8s applications to workload clusters. It allows users to specify the source of the cdk8s application, any input values, and the target clusters for deployment.

 ### Cdk8sAppProxySpec Fields
 
 - **gitRepository**: (Optional) Specifies the Git repository for the cdk8s application. `gitRepository` must be specified.
     - **url**: (Required) The Git repository URL.
-    - **reference**: (Optional) The Git reference (branch, tag, or commit) to check out.
-    - **path**: (Optional) The path within the repository where the cdk8s application is located. Defaults to the root.
-- **values**: (Optional) A string containing values to be passed to the cdk8s application, typically in YAML or JSON format. This can be used to customize the deployment. The controller supports Go templating within this field, allowing dynamic values based on cluster properties (e.g., `{{ .Cluster.spec.clusterNetwork.apiServerPort }}`).
+    - **reference**: (Required) The Git reference (branch, tag, or commit) to check out.
+    - **referencePollInterval**: (Optional) The interval at which the controller checks for changes in the Git repository. Defaults to `5m`.
+    - **path**: (Required) The path within the repository where the cdk8s application is located. Defaults to the root.
 - **clusterSelector**: (Required) A `metav1.LabelSelector` that specifies which workload clusters the cdk8s application should be deployed to. The controller will watch for clusters matching this selector in the same namespace as the `Cdk8sAppProxy` resource.
