+You'll need to use the `gcloud` CLI tool to get the credentials such as `masterUrl` and `caCertData`. You can do this by running the following command:
 
 ```bash
 gcloud container clusters get-credentials clustername --region myregion --project projectid
 ```
 
 You'll need to update the following arguments above with your own values:
-- `clustername` is the name of your cluster.
-- `myregion` is the region your cluster is in, e.g., `europe-west2`.
-- `projectid` is the ID of your Google Cloud project.
+- `clusterId` is the name of your cluster.
+- `clusterZone` is the region your cluster is in, e.g., `europe-west2`.
+- `clusterProjectId` is the ID of your Google Cloud project.
 
 Once you've run this command, you can now access your config with `kubectl config view --minify --flatten`, so you can replace `caCertData`, `masterUrl` and `username`.
