+# Developing Cluster API Provider Huawei for with Tilt
+
+## Overview
+
+This document describes how to use [kind](https://kind.sigs.k8s.io) and [Tilt](https://tilt.dev) for a simplified
+workflow that offers easy deployments and rapid iterative builds.
+
+## Prerequisites
+
+1. [Docker](https://docs.docker.com/install/): v19.03 or newer (on MacOS e.g. via [ObrStack](https://orbstack.dev/))
+2. [kind](https://kind.sigs.k8s.io): v0.25.0 or newer
+3. [Tilt](https://docs.tilt.dev/install.html): v0.30.8 or newer
+4. [kustomize](https://github.com/kubernetes-sigs/kustomize): provided via `make kustomize`
+5. [envsubst](https://github.com/drone/envsubst): provided via `make envsubst`
+6. [helm](https://github.com/helm/helm): v3.7.1 or newer
+7. Clone the [Cluster API](https://github.com/kubernetes-sigs/cluster-api) repository
+   locally
+8. Clone the provider(s) you want to deploy locally as well
+
+## Getting started
+
+### Create a tilt-settings file
+
+create a `tilt-settings.yaml` file and place it in your local copy of `cluster-api`. Here is an example that uses the components from the CAPI repo:
+
+```yaml
+default_registry: localhost:5000
+enable_providers:
+- huawei
+- kubeadm-bootstrap
+- kubeadm-control-plane
+provider_repos:
+- ../cluster-api-provider-huawei
+template_dirs:
+  huawei:
+  - ../cluster-api-provider-huawei/templates
+kustomize_substitutions:
+  CLOUD_SDK_AK: "xxxxxxxx"
+  CLOUD_SDK_SK: "xxxxxxxx"
+
+  HC_REGION: "cn-east-5"
+  HC_SSH_KEY_NAME: "default"
+  KUBERNETES_VERSION: "v1.26.15"
+  CLUSTER_NAME: "hello"
+  CONTROL_PLANE_MACHINE_COUNT: "1"
+  WORKER_MACHINE_COUNT: "1"
+  HC_CONTROL_PLANE_MACHINE_TYPE: "c6.xlarge.2"
+  HC_NODE_MACHINE_TYPE: "c6.xlarge.2"
+```
+
+
+### Create a kind cluster and run Tilt!
+
+To create a pre-configured kind cluster (if you have not already done so) and launch your development environment, run
+
+```bash
+make tilt-up
+```
