# Usage

Add the latest version of northstar to your `Cargo.toml`.

## Manually

```toml
northstar = "0.3.0" # check crates.io for the latest version
```

## Automatically

cargo add northstar
```

# Generating a key & certificate

Run
```sh
mkdir cert && cd cert
openssl req -x509 -nodes -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365
