## Prerequisites
Before you begin, make sure your development environment includes `Node.js®` and an npm package manager.
To use the Angular framework, you should be familiar with the following:
* [JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript/A_re-introduction_to_JavaScript)
* [HTML](https://developer.mozilla.org/docs/Learn/HTML/Introduction_to_HTML)
* [CSS](https://developer.mozilla.org/docs/Learn/CSS/First_steps)
Knowledge of [TypeScript](https://www.typescriptlang.org/) is helpful, but not required.

### Node.js
Make sure your development environment includes `Node.js®` and an npm package manager.
Angular requires a [current, active LTS, or maintenance LTS](https://nodejs.org/about/releases/) version of `Node.js`. See the `engines` key for the specific version requirements in our [package.json](https://unpkg.com/@angular/cli/package.json).
* To check your version, run `node -v` in a terminal/console window.
