+1. Install Gitkube CLI:
+   - Linux/MacOS
+   ``` bash
+   curl https://raw.githubusercontent.com/hasura/gitkube/master/gimme.sh | bash
+   ```
+   - Windows: download the latest [release](https://github.com/hasura/gitkube/releases) and add it to your `PATH`.
+
+2. Use Gitkube CLI to install Gitkube on the cluster:
+   ```bash
+   gitkube install
+   ```
+
 #### Provider walkthroughs
 
 The above installation steps work on most Kubernetes clusters. Detailed walkthroughs for few specific providers are also available:
