This page describes the Angular documentation at a high level.
If you're new to Angular, you may want to visit "[Learning Angular](guide/learning-angular)" first.

本页是 Angular 文档的概述。
如果你刚接触 Angular，请先访问“[学习 Angular](guide/learning-angular)”。

## Themes

## 主题

The documentation is divided into major thematic sections, each
a collection of pages devoted to that theme.

本文档分成几大主题区，每个区包含一组围绕自己主题的页面。

A few early pages are written as tutorials and are clearly marked as such.
The rest of the pages highlight key points in code rather than explain each step necessary to build the sample.
You can always get the full source through the #{_liveLink}s.

少量早期页面是作为教程来写的，并被清晰的标注出来。
其它页面的目的是展示代码中的关键点，而不是解释构建这个范例所需的每一个步骤。
可以通过在线例子的链接找到完整的源代码。

## Code samples

## 代码例子

Each page includes code snippets from a sample application that accompanies the page.
You can reuse these snippets in your applications.

每章都包含了该章附带例子应用的代码片段。可以在你的应用中重用这些代码片段。

Look for a link to a running version of that sample, often near the top of the page,
such as this <live-example nodownload name="architecture"></live-example> from the [Architecture](guide/architecture) page.
<span if-docs="ts">
The link launches a browser-based, code editor where you can inspect, modify, save, and download the code.
</span>

查找这些例子在线版本的链接，通常在页面的开头部分附近。
例如[架构](guide/architecture)章的<live-example name="architecture"></live-example>。
<span if-docs="ts">
该链接启动浏览器代码编辑器，你可以查看、修改、保存和下载代码。
</span>

Alternatively, you can run the example locally, next to those `live-example` links you have a <a href="/resources/zips/architecture/architecture.zip">download link</a>.
Just download, unzip, run `npm install` to install the dependencies and run it with `npm start`.

不过，你也可以在本地运行这个例子，你可以点击<a href="/resources/zips/architecture/architecture.zip">下载链接</a>来下载。
只要下载、unzip、运行`npm install`安装依赖，然后运行`npm start`就可以了。
