# Install AIF

The public CLI quickstart supports a supported macOS or Linux environment. Confirm [system requirements](/getting-started/requirements) first if you plan to use the full local model.

## Install with one command

```sh title="Terminal"
curl -fsSL https://aif.harden.run/install.sh | sh
```

Open a new shell after the installer finishes. You should then be able to run `aif`.

## What happens next

The installer is the only step that installs the client. Continue to the [quickstart](/getting-started/quickstart) to configure a detected agent, run the safe demo, and open the local decision history.

## If installation does not finish

Run the read-only health checks below after opening a new shell:

```sh title="Terminal"
aif status
aif doctor
```

If the output does not explain the repair, see [troubleshooting](/operations/troubleshooting) or [book a support call](https://calendar.app.google/GdL3BvBuagny6Kh5A).
