+# Kind
+
+Kind *(Kubernetes IN Docker)* is a tool for running local Kubernetes clusters using
+Docker container as *nodes*.
+It is primarily used for testing Kubernetes itself, or for developing Kubernetes
+applications in a local environment.
+
+::: warn
+The documentation below assumes you are **not** using [`sysbox`][sysbox] as you Docker
+runtime.
+:::
+
+## Custom Configuration
+
+Custom configuration can be stored in a `yaml` file of your choice and used with
+the `kind create cluster --config my-config.yaml`.
+
+### Cluster IP
+
+For security reasons, a *kind* cluster is configured by default to be accessible at
+`127.0.0.1`.
+When using a remote Docker engine, it's necessary to adjust this setting, as the IP
+address resolves to the internal address of the current *workspace*.
+
+To make the cluster accessible on the network of the running host, change the listening
+address to `0.0.0.0` *(or to a specific host IP)*:
+
+```yaml
+kind: Cluster
+apiVersion: kind.x-k8s.io/v1alpha4
+networking:
+  apiServerAddress: 0.0.0.0
+# ... more custom configurations follow
+```
+
+Once deployed, you will need to update the `KUBECONFIG` to communicate with the API server
+using the host IP for the `cluster.server` address.
+
+```yaml
+apiVersion: v1
+clusters:
+- cluster:
+    server: https://192.168.1.120:6443
+    certificate-authority-data: DATA+OMITTED
+  name: created-by-kind
+# ... more custom configurations follow
+```
