+# Kind Provider Example
+
+This example demonstrates how to use the Kind provider to manage multiple Kubernetes clusters created with Kind (Kubernetes in Docker).
+
+## Overview
+
+The Kind provider allows you to:
+1. Automatically discover and connect to multiple Kind clusters
+2. Run controllers that can operate across all discovered clusters
+3. Test multicluster scenarios locally using Docker containers
+
+## Prerequisites
+
+- [Kind](https://kind.sigs.k8s.io/docs/user/quick-start/) installed and available in your PATH
+- Docker running on your machine
+- `kubectl` configured to access Kind clusters
+
+## Usage
+
+### 1. Create Kind Clusters
+
+First, create multiple Kind clusters for testing:
+
+```bash
+kind create cluster --name fleet-alpha
+kind create cluster --name fleet-beta
+```
+
+This will create two Kind clusters:
+- `fleet-alpha` accessible via context `kind-fleet-alpha`
+- `fleet-beta` accessible via context `kind-fleet-beta`
+
+### 2. Run the Example
+
+Start the multicluster operator:
+
+```bash
+go run ./main.go
+```
+
+The operator will automatically discover the Kind clusters and connect to them.
+
+### 3. Observe Cross-Cluster Operations
+
+In separate terminals, monitor events across both clusters to see the multicluster operations in action:
+
+```bash
+# Terminal 1: Monitor fleet-alpha cluster
+kubectl get events -A --context kind-fleet-alpha --watch
+
+# Terminal 2: Monitor fleet-beta cluster  
+kubectl get events -A --context kind-fleet-beta --watch
+```
+
+## How It Works
+
+1. The Kind provider automatically discovers Kind clusters by:
+   - Scanning for Kind cluster using `"sigs.k8s.io/kind/pkg/cluster"`
+   - Connecting to clusters that match the Kind naming pattern (`fleet-*`)
+2. For each discovered cluster, it engages multicluster-runtime.
+3. Your controllers can then operate across all discovered clusters
+
+## Cleanup
+
+To clean up the Kind clusters when you're done:
+
+```bash
+kind delete cluster --name fleet-alpha
+kind delete cluster --name fleet-beta
+```
