# CLI

To use `pino-stackdriver` from the command line, you need to install it globally:

```bash
npm install -g pino-stackdriver
```

## Example

Given an application `foo` that logs via pino, a stackdriver log project `bar` and credentials in the file `/credentials.json`, you would use `pino-stackdriver` like so:

```bash
node foo | pino-stackdriver --project bar --credentials /credentials.json
```
