# CLI Installation

> Get started with the Nudgen CLI on macOS, Linux, or Windows.

## Quick Install

The easiest way to install the Nudgen CLI is using our one-liner install script.

### macOS & Linux

Run the following command in your terminal:

```bash theme={null}
curl -fsSL https://cli.nudgen.net | bash
```

### Via Go

If you have Go 1.22+ installed, you can install the CLI directly:

```bash theme={null}
go install github.com/Nudgen-Marketing/nudgen-cli@latest
```

### From Source

If you have Go 1.22+ installed, you can build from source:

```bash theme={null}
git clone https://github.com/Nudgen-Marketing/nudgen-cli.git
cd nudgen-cli
make build
```

The binary will be available at `./bin/nudgen`.

## Initial Setup

Once installed, verify the installation by checking the version:

```bash theme={null}
nudgen version
```

### Authentication

To start using the CLI, you need to authenticate with a Personal Access Token (PAT).

1. Run the login command:
   ```bash theme={null}
   nudgen login
   ```
2. Follow the interactive prompts to enter your token.
3. Verify your identity:
   ```bash theme={null}
   nudgen whoami
   ```

### Updating

To update to the latest version, simply run the install script again or use the built-in update command (if available):

```bash theme={null}
nudgen update
```

## Security

Nudgen CLI uses the system keychain to store your PAT securely. We never log or output raw tokens in any command output.
