# Installation

> Install the LinkModel CLI and verify that it is available on your PATH.

Install the CLI with npm:

```bash theme={null}
npm install -g linkmodel-cli
```

Verify the install:

```bash theme={null}
lkm --version
lkm --help
```

The package installs two command names:

| Command     | Description                               |
| ----------- | ----------------------------------------- |
| `lkm`       | Short command used throughout these docs. |
| `linkmodel` | Descriptive alias with the same behavior. |

Both commands call the same CLI.

## Update

Use npm to update the global package:

```bash theme={null}
npm install -g linkmodel-cli@latest
```

Check the installed version after updating:

```bash theme={null}
lkm --version
```
