 # Local Development
 Tilt is favoured by most Cluster API projects for local development, it offers a simple way of creating a local development environment.
+Cluster API includes its own Tiltfile that can be used to run Cluster API Operator on a local Kind cluster.
+
+## Clone the Cluster API repository
+
+Clone the Cluster API repository on the same level folder where Cluster API Operator located:
 
-## Create a kind cluster
-We'll need to create a kind cluster to deploy the operator to. This cluster will be used to deploy `cluster-api-operator` to, along with all dependencies such as `cert-manager`
 ```bash
-kind create cluster
+$ git clone https://github.com/kubernetes-sigs/cluster-api.git
+```
+
+Afterward your folder structure should look like this:
+
+```
+some-folder/
+├── cluster-api
+└── cluster-api-operator
+```
+
+## Set up Tilt settings in `cluster-api` folder
+
+Refer to [this guide](https://cluster-api.sigs.k8s.io/developer/core/tilt.html) to set up Tilt for Cluster API.
+
+In particular, for our purposes we only need to set up `tilt-settings.yaml` in Cluster API to enable Cluster API Operator. Add the following fields to the lists in `tilt-settings.yaml`:
+
+```yaml
+provider_repos:
+- "../cluster-api-operator"
+enable_providers:
+- capi-operator
+enable_core_provider: false
 ```
 
 ## Run Tilt
-Once the cluster is live, and you've confirmed you're using the correct context, you can simply run:
+
+From `cluster-api` folder run:
+
 ```bash
-tilt up
+$ make tilt-up
 ```
 
-That's it! Tilt will automatically reload the deployment to your local cluster every time you make a code change.
+That's it! Tilt will automatically reload the deployment to your local cluster every time you make a code change and able to debug deployed code.
