How to: Reduce the repetition
[Normally up to a dozen commands](https://cert-manager.io/docs/installation/kubernetes/) (including finding and downloading helm), now just one. No searching for the correct CRD to apply, no trying to install helm, no trying to find the correct helm repo to add:

```bash
arkade install cert-manager
```

Other common tools:

```bash
arkade install ingress-nginx

arkade install metrics-server
```
