How to: Automatic download of tools
When required, tools, CLIs, and the helm binaries are downloaded and extracted to `$HOME/.arkade`.

If installing a tool which uses helm3, arkade will check for a cached version and use that, otherwise it will download it on demand.

Did you accidentally run arkade as root? **Running as root is not required**, and will mean your KUBECONFIG environment variable will be ignored. You can revert this using [the notes on release 0.1.18](https://github.com/alexellis/arkade/releases/tag/0.1.8).
