Good tools make application development quicker and easier to maintain than

if you did everything by hand.

The goal in this guide is to build and run a simple Angular

application in TypeScript, using the Angular CLI

while adhering to the [Style Guide](./guide/style-guide.html) recommendations that

benefit _every_ Angular project.

|

|

By the end of the chapter, you'll have a basic understanding of development with the CLI
|
||||
and a foundation for both these documentation samples and for real world applications.
|
||||
|
||||
You'll pursue these ends in the following high-level steps:
|
||||
|
||||
|
||||
1. [Set up](#devenv) the development environment.
|
||||
2. [Create](#create-proj) a new project and skeleton application.
|
||||
3. [Serve](#serve) the application.
