# Preparing your environment

### Prerequisites <a href="#prerequisite" id="prerequisite"></a>

The Singular Widget SDK requires a local installation of Node.js. Download it from <https://nodejs.org/en/>.

{% hint style="info" %}
This document describes how to install singular-cli. For details about Singular's other CLIs, singularwidget-cli and singularapp-cli, see <https://github.com/singularlive/> and <https://www.npmjs.com/~singularlive>.
{% endhint %}

### Installing the Singular CLI <a href="#install-singular-cli" id="install-singular-cli"></a>

After installing Node.js, open a console and install `singular-cli` by running this command:

```bash
npm install singular-cli -g
```

After the installing the CLI, console commands to create and deploy Singular widgets and apps will become available.

The `create` commands serve to clone the Singular boilerplates into a specified folder.

The `deploy` commands check, package, and upload your widget or app code to Singular.live. Every widget and app is identified by a unique deploy key. Generating a deploy key is covered [here](/software-development-kits/widget-sdk/getting-started.md#deploying-an-app).

**Create Singular widget boilerplate**

```bash
singular createwidget <folder name>
```

**Deploy a Singular widget**

```bash
singular deploywidget <folder name>
```

For more information about the Singlar.live CLI see <https://github.com/singularlive/singular-cli>.
