# CLI

## Quick Install

Run the install script to download the latest Nullify CLI binary:

```bash
curl -sSfL https://raw.githubusercontent.com/Nullify-Platform/cli/main/install.sh | sh -s -- --host api.<TENANT>.nullify.ai
```

Replace `<TENANT>` with your organization name (e.g. `api.acme.nullify.ai`).

This will:

* Detect your OS and architecture (macOS, Linux; amd64, arm64)
* Download the latest release from [GitHub Releases](https://github.com/Nullify-Platform/cli/releases)
* Verify the SHA256 checksum
* Install the binary to `/usr/local/bin/nullify` (or `~/.local/bin/`)
* Configure the CLI to connect to your Nullify instance

## Verify Installation

```bash
nullify --version

## Configuration

The CLI connects to your Nullify instance using the `--host` flag or `NULLIFY_HOST` environment variable:

```bash
# Set via flag
nullify --host api.<TENANT>.nullify.ai <command>

# Or set via environment variable
export NULLIFY_HOST=api.<TENANT>.nullify.ai
nullify <command>
```
