# Install

> Install the iii engine and set up your development environment.

## 1. Install iii

Install the iii engine:

```bash theme={"theme":{"light":"catppuccin-latte","dark":"dark-plus"}}
curl -fsSL https://install.iii.dev/iii/main/install.sh | sh
```

## 2. Verify installation

Check that iii has installed correctly with the following command. It should return a version
number.

```bash theme={"theme":{"light":"catppuccin-latte","dark":"dark-plus"}}
iii --version
```

<Info title="Engine and SDK versions">
  The engine and SDK packages can have different patch versions within the same minor line. Keep the
  engine and SDKs on the same minor version, for example `0.11.x`, unless a release note says
  otherwise.
