+# Crossplane Azure Integration
+
+## Overview
+
+This project provides a set of Helm templates for managing Azure and AWS resources using
+Crossplane. It enables the creation and management of Azure Virtual Networks (VNet) and
+associated resource groups through declarative configuration.
+
+## Prerequisites
+
+- **Crossplane**: You must have [Crossplane](https://crossplane.io/docs/) installed in your Kubernetes cluster.
+
+## Configuration
+
+### Values File
+
+Edit the `values.yaml` file to specify your Azure resources:
+
+- **location**: The Azure region where the resources will be created.
+- **defaultSubscription**: The default Azure subscription to use if no specific providerConfigRef is provided.
+- **defaultRgName**: The default resource group name.
+- **vnet**: Define your Virtual Networks here resource group associations.
+
+**Example `values.yaml`:**
+
+```yaml
+location: North Europe
+subscription: default
+defaultRgName: rgcrossplane
+resourceGroup:
+  rgcrossplane:
+    location: North Europe
+  rgcrossplane1:
+    location: North Europe
+vnet:
+  vnet-crossplane1:
+    cidrBlock: 10.0.0.0/16
+    rgName: rgcrossplane1
+    providerConfigRef:
+      name: default
+  vnet-crossplane2:
+    cidrBlock: 10.0.0.0/16
+```
