+====================
+
+After installing Yii, you have a working Yii application that can be accessed via
+the URL `http://hostname/basic/web/index.php` or `http://hostname/index.php`, depending
+upon your configuration. This section will introduce the application's built-in functionality,
+how the code is organized, and how the application handles requests in general.
+
+> Info: For simplicity, throughout this "Getting Started" tutorial, it's assumed that you have set `basic/web`
+  as the document root of your Web server, and configured, the URL for accessing
+  your application to be `http://hostname/index.php` or something similar.
+  For your needs, please adjust the URLs in our descriptions accordingly.
+
+
+Functionality <a name="functionality"></a>
+-------------
+
+The basic application installed contains four pages:
+
+* The homepage, displayed when you access the URL `http://hostname/index.php`,
+* the "About" page,
+* the "Contact" page, which displays a contact form that allows end users to contact you via email,
+* and the "Login" page, which displays a login form that can be used to authenticate end users. Try logging in
+  with "admin/admin", and you will find the "Login" main menu item will change to "Logout".
+
+These pages share a common header and footer. The header contains a main menu bar to allow navigation
+among different pages.
+
+You should also see a toolbar at the bottom of the browser window.
+This is a useful [debugger tool](tool-debugger.md) provided by Yii to record and display a lot of debugging information, such as log messages, response statuses, the database queries run, and so on.
+
+
+Application Structure <a name="application-structure"></a>
+---------------------
+
+The most important directories and files in your application are (assuming the application's root directory is `basic`):
+
+```
+basic/                  application base path
+    composer.json       used by Composer, describes package information
+    config/             contains application and other configurations
+        console.php     the console application configuration
+        web.php         the Web application configuration
+    commands/           contains console command classes
+    controllers/        contains controller classes
+    models/             contains model classes
+    runtime/            contains files generated by Yii during runtime, such as logs and cache files
+    vendor/             contains the installed Composer packages, including the Yii framework itself
+    views/              contains view files
+    web/                application Web root, contains Web accessible files
+        assets/         contains published asset files (javascript and css) by Yii
+        index.php       the entry (or bootstrap) script for the application
+    yii                 the Yii console command execution script
+```
+
+In general, the files in the application can be divided into two types: those under `basic/web` and those
+under other directories. The former can be directly accessed via HTTP (i.e., in a browser), while the latter can not and should not be.
+
+Yii implements the [model-view-controller (MVC)](http://wikipedia.org/wiki/Model-view-controller) design pattern,
+which is reflected in the above directory organization. The `models` directory contains all [model classes](structure-models.md),
+the `views` directory contains all [view scripts](structure-views.md), and the `controllers` directory contains
+all [controller classes](structure-controllers.md).
+
+The following diagram shows the static structure of an application.
+
+![Static Structure of Application](images/application-structure.png)
+
+Each application has an entry script `web/index.php` which is the only Web accessible PHP script in the application.
+The entry script takes an incoming request and creates an [application](structure-applications.md) instance to handle it.
+The [application](structure-applications.md) resolves the request with the help of its [components](concept-components.md),
+and dispatches the request to the MVC elements. [Widgets](structure-widgets.md) are used in the [views](structure-views.md)
+to help build complex and dynamic user interface elements.
+
+
+Request Lifecycle <a name="request-lifecycle"></a>
+-----------------
+
+The following diagram shows how an application handles a request.
+
+![Request Lifecycle](images/application-lifecycle.png)
+
+1. A user makes a request to the [entry script](structure-entry-scripts.md) `web/index.php`.
+2. The entry script loads the application [configuration](concept-configurations.md) and creates
+   an [application](structure-applications.md) instance to handle the request.
+3. The application resolves the requested [route](runtime-routing.md) with the help of
+   the [request](runtime-requests.md) application component.
+4. The application creates a [controller](structure-controllers.md) instance to handle the request.
+5. The controller creates an [action](structure-controllers.md) instance and performs the filters for the action.
+6. If any filter fails, the action is cancelled.
+7. If all filters pass, the action is executed.
+8. The action loads a data model, possibly from a database.
+9. The action renders a view, providing it with the data model.
+10. The rendered result is returned to the [response](runtime-responses.md) application component.
+11. The response component sends the rendered result to the user's browser.
