 ### For apps that use routing

 If your app uses routing, you need to teach the server to always return 
 `index.html` when the user asks for an HTML page
 for reasons explained in the [Deployment](guide/deployment#fallback) guide.
 
+如果应用要使用路由，就要让服务器在用户要求 HTML 页面时始终返回`index.html`。
+此中原因，在[发布](guide/deployment#fallback)一章中有解释。

 Everything seems fine while you move about _within_ the app. 
 But you'll see the problem right away if you refresh the browser
 or paste a link to an app page (called a "deep link") into the browser address bar.
 
+当我们在应用*内部*移动时，看起来一切正常。但是如果刷新浏览器，或者在地址栏中输入一个到具体页面的地址（也就是"深链接"）时，问题就来了。

 You'll most likely get a *404 - Page Not Found* response from the server
 for any address other than `/` or `/index.html`.
 
+我们很可能从服务器得到得到*404 - 页面不存在* —— 只有 `/` 或 `/index.html` 例外。

 You have to configure the server to return `index.html` for requests to these "unknown" pages.

 This section walks through the steps to adapt the QuickStart application.
