docs: Add basic tool help pages for SDK and AVD Manager.

The SDK Manager page is needed particularly as a reference by
some pages rather than pointing to the installation guide.

   <p>The AVD Manager is an easy to use user interface to manage your AVD (Android Virtual Device)
   configurations. An AVD is a device configuration for the Android emulator that allows you to
   model different configurations of Android-powered devices. When you start the AVD Manager in Eclipse 
-  or run the <code>android</code> tool on the command line, you will see the AVD Manager as shown in
-  figure 1:</p>
+  or navigate to your SDK's {@code tools/} directory and execute
+  <code>android avd</code>. You will see the AVD Manager as shown in
+  figure 1.</p>

+page.title=SDK Manager
+@jd:body
+
+
+<p>The Android SDK separates tools, platforms, and other components into packages you can
+  download using the SDK Manager.</p>
+
+<p>You can launch the SDK Manager in one of the following ways:</p>
+<ul>
+  <li>On Windows, double-click the <code>SDK Manager.exe</code> file at the root of the Android
+SDK directory.</li>
+  <li>On Mac or Linux, open a terminal and navigate to the <code>tools/</code> directory in the
+Android SDK, then execute <code>android sdk</code>.</li>
+</ul>
+
+<p>You can select which packages you want to download by toggling the checkboxes on the left, then
+click <strong>Install</strong> to install the selected packages.</p>
+
+<img src="{@docRoot}images/sdk_manager_packages.png" alt="" />
+<p class="img-caption"><strong>Figure 1.</strong> The Android SDK Manager shows the
+SDK packages that are available, already installed, or for which an update is available.</p>
+
+
+<h2 id="Recommended">Recommended Packages</h2>
+
+<p>Here's an outline of the packages required and those we recommend you use:
+</p>
+
+<dl>
+  <dt>SDK Tools</dt>
+  <dd><strong>Required.</strong> Your new SDK installation already has the latest version. Make sure
+you keep this up to date.</dd>
+  <dt>SDK Platform-tools</dt>
+  <dd><strong>Required.</strong> You must install this package when you install the SDK for
+the first time.</dd>
+  <dt>SDK Platform</dt>
+  <dd><strong>Required.</strong>You must download <em>at least one platform</em> into your
+environment so you're able to compile your application. In order to provide the best user experience
+on the latest devices, we recommend that you use the latest platform version as your build target.
+You'll still be able to run your app on older versions, but you must build against the latest
+version in order to use new features when running on devices with the latest version of Android.
+  <p>To get started, download the latest Android version, plus the lowest version you plan
+  to support (we recommend Android 2.2 for your lowest version).</p></dd>
+  <dt>System Image</dt>
+  <dd>Recommended. Although you might have one or more Android-powered devices on which to test
+ your app, it's unlikely you have a device for every version of Android your app supports. It's
+a good practice to download system images for all versions of Android your app supports and test
+your app running on them with the <a href="{@docRoot}tools/devices/emulator.html">Android emulator</a>.</dd>
+  <dt>Android Support</dt>
+  <dd>Recommended. Includes a static library that allows you to use some of the latest
+Android APIs (such as <a href="{@docRoot}guide/components/fragments.html">fragments</a>,
+plus others not included in the framework at all) on devices running
+a platform version as old as Android 1.6. All of the activity templates available when creating
+a new project with the <a href="{@docRoot}tools/sdk/eclipse-adt.html">ADT Plugin</a>
+require this. For more information, read <a
+href="{@docRoot}tools/extras/support-library.html">Support Library</a>.</dd>
+  <dt>SDK Samples</dt>
+  <dd>Recommended. The samples give you source code that you can use to learn about
+Android, load as a project and run, or reuse in your own app. Note that multiple
+samples packages are available &mdash; one for each Android platform version. When
+you are choosing a samples package to download, select the one whose API Level
+matches the API Level of the Android platform that you plan to use.</dd>
+</dl>
+
+<p class="note"><strong>Tip:</strong> For easy access to the SDK tools from a command line, add the
+location of the SDK's <code>tools/</code> and
+<code>platform-tools</code> to your <code>PATH</code> environment variable.</p>
