## Installation
There are several ways to install `np-viewer`. The recommended installation is via the `kubectl` plugin manager
called [`krew`](https://github.com/kubernetes-sigs/krew).
### Via krew
Krew is a `kubectl` plugin manager. If you have not yet installed `krew`, get it at
[https://github.com/kubernetes-sigs/krew](https://github.com/kubernetes-sigs/krew).
Then installation is as simple as
```bash
kubectl krew install np-viewer
```
The plugin will be available as `kubectl np-viewer`, see [doc/USAGE](doc/USAGE.md) for further details.
