# Installation

> Install the CLI and authenticate it with your Typecast API key.

## Install

<Tabs>
  <Tab title="Homebrew">
    ```bash theme={null}
    brew install neosapience/tap/cast
    ```
  </Tab>

  <Tab title="Go">
    ```bash theme={null}
    go install github.com/neosapience/cast@latest
    ```
  </Tab>
</Tabs>

## Log in

Run the login command and enter your Typecast API key when prompted:

```bash theme={null}
cast login
```

You can also pass the key directly:

```bash theme={null}
cast login <api_key>
```

Get your key from the [Typecast API Console](https://typecast.ai/developers/api).

## Verify the install

```bash theme={null}
cast "Hello, world!"
```

If you hear audio playback, CLI is ready.

<Tip>
  Use `cast "Hello, world!" --out hello.wav` if you want to verify file generation instead of local audio playback.
