# CLI Installation

> Install and use the SendyKit CLI for health, doctor, brands, billing, and licensing operations

## Install the CLI

The standard installer places the `sendykit` binary on your server:

```bash theme={null}
curl -sSL https://install.sendykit.dev | bash
```

If you already have SendyKit installed, confirm the CLI is available:

```bash theme={null}
sendykit --help
```

## Useful first commands

```bash theme={null}
sendykit health
sendykit doctor
sendykit brands list
sendykit license status
```

## What the CLI is for

Use the CLI when you want:

* server-side operational checks
* readiness and doctor output in scripts
* licensing inspection and verification
* brand, campaign, and subscriber operations without opening the admin UI
