# Wasmer-JS CLI

The Wasmer-JS command line interface (CLI) uses a modern Javascript Workflow, which depends on [Node.js](https://nodejs.org/en/).

## Install Wasmer-JS CLI

To install the Wasmer-JS CLI globally on your system, run the following command:

```bash
$ npm install -g @wasmer/cli
```

The Wasmer-JS CLI tool should now be installed. To test it, run the command `wasmer-js --help` and you should see output similar to the following:

```bash
$ wasmer-js --help
