+# CAPT development setup with the Playground
+
+This document describes how to set up a development environment for CAPT using the Playground.
+
+The following repositories are required for the CAPT development setup.
+
+- `github.com/tinkerbell/cluster-api-provider-tinkerbell`
+- `github.com/tinkerbell/playground`.
+
+## Setup
+
+1. Fork the CAPT repository in GitHub.
+1. Clone CAPT and the Playground repositories to your local machine.
+
+    ```bash
+    git clone [email protected]:<your user>/cluster-api-provider-tinkerbell.git
+    git clone https://github.com/tinkerbell/playground.git
+    ```
+
+1. Create a local release in CAPT.
+
+    ```bash
+    cd cluster-api-provider-tinkerbell
+    make release-local
+    ```
+
+1. In the `config.yaml`, set `capt.providerRepository` to the local release directory, minus the version. For example: `capt.providerRepository: /home/user/cluster-api-provider-tinkerbell/out/release/infrastructure-tinkerbell`
+
+    ```bash
+    cd playground/capt
+    sed -i 's|providerRepository:.*|providerRepository: /home/user/cluster-api-provider-tinkerbell/out/release/infrastructure-tinkerbell|' config.yaml
+    ```
+
+1. Create the CAPT playground. Once the playground gets to the prompt waiting for user input, leave it for now and move on to the next step in this doc.
+
+    ```bash
+    cd playground/capt
+    task create-playground
+    ```
+
+1. Deploy the local CAPT code.
+
+    ```bash
+    cd cluster-api-provider-tinkerbell
+    export KUBECONFIG=<playground repo>/capt/output/kind.kubeconfig
+    tilt up --stream
+    ```
+
+1. Enter `y` in the CAPT Playground prompt and follow the post creation instructions.
