+# Quick Start with Kind
+> [!NOTE]
+> kind does not require kubectl, but you will not be able to perform some of the examples in our docs without it. To install kubectl see the upstream kubectl installation docs.
+
+## Install 
+
+**macOS:**
+```bash
+# For Intel Macs
+[ $(uname -m) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.26.0/kind-darwin-amd64
+# For M1 / ARM Macs
+[ $(uname -m) = arm64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.26.0/kind-darwin-arm64
+chmod +x ./kind
+mv ./kind /some-dir-in-your-PATH/kind
+```
+
+**Linux:**
+```bash
+# For AMD64 / x86_64
+[ $(uname -m) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.26.0/kind-linux-amd64
+# For ARM64
+[ $(uname -m) = aarch64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.26.0/kind-linux-arm64
+chmod +x ./kind
+sudo mv ./kind /usr/local/bin/kind
+```
+
+## Setup cluster with port forwarding 
+
+> [!NOTE]
+> On the host computer, `localhost:80` should be accessible.
+
+```bash
+cat <<EOF | kind create cluster --config=-
+kind: Cluster
+apiVersion: kind.x-k8s.io/v1alpha4
+nodes:
+- role: control-plane
+  extraPortMappings:
+  - containerPort: 80
+    hostPort: 80
+    protocol: TCP
+  - containerPort: 443
+    hostPort: 443
+    protocol: TCP
+EOF
+```
+
+Deploy the ingress nginx controller:
+```bash
+kubectl apply -f https://kind.sigs.k8s.io/examples/ingress/deploy-ingress-nginx.yaml
+```
+
+Wait the nginx controller to be ready:
+```bash
+kubectl wait --namespace ingress-nginx \
+  --for=condition=ready pod \
+  --selector=app.kubernetes.io/component=controller \
+  --timeout=90s
+```
+
+Add host entries to be able to work with ingresses from the host machine:
+```bash
+sudo cp -p /etc/hosts /tmp/hosts
+echo "127.0.0.1       huly.example" | sudo tee -a /etc/hosts
+echo "127.0.0.1       account.huly.example" | sudo tee -a /etc/hosts
+```
+
+Deploy Huly with `kubectl`:
+
+```bash
+kubectl apply -R -f .
+```
+
+Wait until the front app is coming up:
+```bash
+kubectl wait --for=condition=Avaiable deployment/front --timeout 3m
+```
+
+Now, launch your web and and (enjoy Huly!)[http://huly.example]!
+
+
+## Cleanup
+
+Restore hosts file:
+```bash
+sudo mv /tmp/hosts /etc/hosts
+```
+
+Cleanup Huly:
+```bash
+kubectl delete -R -f .
+```
+
+Delete kind cluster:
+```bash
+kind delete cluster
+```
