+This folder is a [kustomize application](https://kubectl.docs.kubernetes.io/references/kustomize/glossary/#application) that stands up a running instance of go-httpbin in a Kubernetes cluster.
+
+You may wish to utilise this as a [remote application](https://kubectl.docs.kubernetes.io/references/kustomize/kustomization/resource/), e.g.
+
+```yaml
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+commonLabels:
+  app.kubernetes.io/name: httpbin
+resources:
+  - github.com/mccutchen/go-httpbin/kustomize
+images:
+  - name: mccutchen/go-httpbin
+```
+
+To expose your instance to the interner, you could add an `Ingress` in an overlay:
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+  name: httpbin
+spec:
+  ingressClassName: myingressname
+  rules:
+    - host: my-go-httpbin.com
+      http:
+        paths:
+          - path: /
+            pathType: Prefix
+            backend:
+              service:
+                name: httpbin
+                port:
+                  name: http
+  tls:
+   - hosts:
+       - my-go-httpbin.com
+     secretName: go-httpbin-tls
+```
