+`ngf` is the name of the release, and can be changed to any name you want. This name is added as a prefix to the Deployment name.
+
+If you want the latest version from the **main** branch, add `--version 0.0.0-edge` to your install command.
+
+To wait for the Deployment to be ready, you can either add the `--wait` flag to the `helm install` command, or run the following after installing:
+
+```shell
+kubectl wait --timeout=5m -n nginx-gateway deployment/ngf-nginx-gateway-fabric --for=condition=Available
