## Documentation

#### Linux Deployment

Download [the latest helmet binary](https://github.com/norwik/Helmet/releases). Make it executable from everywhere.

```zsh
$ export LATEST_VERSION=$(curl --silent "https://api.github.com/repos/norwik/Helmet/releases/latest" | jq '.tag_name' | sed -E 's/.*"([^"]+)".*/\1/' | tr -d v)

$ curl -sL https://github.com/norwik/Helmet/releases/download/v{$LATEST_VERSION}/helmet_{$LATEST_VERSION}_Linux_x86_64.tar.gz | tar xz
```
