+  You can use the <strong>Android Studio File &gt; Project Structure</strong> dialog box to
+  change configuration settings for your Android Studio project. This dialog
+  box is useful if you need to change some of the settings you chose when you
+  created the project.
+</p>
+
+<p>
+  The Project Structure dialog box contains the following sections:
+</p>
+
+<ul>
+  <li>
+    <strong>SDK Location:</strong> Sets the location of the JDK, Android SDK,
+    and Android NDK that the project uses.
+  </li>
+
+  <li>
+    <strong>Project:</strong> Sets version information for <a
+    href="{@docRoot}tools/building/plugin-for-gradle.html">Gradle</a> and for
+    the <a href="{@docRoot}tools/building/plugin-for-gradle.html">Android plugin
+    for Gradle</a>.
+  </li>
+
+  <li>
+    <strong>Developer Services:</strong> Contains settings for Android Studio
+    add-in components from Google or third parties.
+  </li>
+
+  <li>
+    <strong>Modules:</strong> Used to set or change various module-specific
+    build settings, including the target and minimum SDK, the app signature,
+    and library dependencies. Most importantly, this is where you change
+    the settings for your project's <em>app</em> module.
+  </li>
+</ul>
+
+<p>
+  The following two sections provide information on the <a href=
+  "#dev-svc">Developer Services</a> and <a href="#modules">Modules</a>
+  sections.
+</p>
+
+<h2 id="dev-svc">
+  Developer Services
+</h2>
+
+<p>
+  The <em>Developer Services</em> section of the <em>Project Structure</em>
+  dialog box contains configuration pages
+  for several services that you can be use with your app. This section
+  contains the following pages:
+</p>
+
+<ul>
+  <li>
+    <strong>AdMob:</strong> Allows you to turn on Google's <a href=
+    "https://developers.google.com/admob/" class="external-link">AdMob</a>
+    component, which helps you understand your users and show them tailored
+    advertisements.
+  </li>
+
+  <li>
+    <strong>Analytics:</strong> Allows you to turn on <a href=
+    "https://developers.google.com/analytics/" class="external-link">Google
+    Analytics</a>, which helps you measure user interactions with your app
+    across various devices and environments.
+  </li>
+
+  <li>
+    <strong>Authentication:</strong> Allows users to use <a href=
+    "https://developers.google.com/identity/sign-in/android/" class=
+    "external-link">Google Sign-In</a> to sign in to your app with their Google
+    accounts.
+  </li>
+
+  <li>
+    <strong>Cloud:</strong> Allows you to turn on <a href=
+    "https://www.firebase.com/" class="external-link">Firebase</a> cloud-based
+    services for your app.
+  </li>
+
+  <li>
+    <strong>Notifications:</strong> Allows you to use <a href=
+    "https://developers.google.com/cloud-messaging/" class=
+    "external-link">Google Cloud Messaging</a> to communicate between your app
+    and your server.
+  </li>
+</ul>
+
+<p>
+  Turning on any of these services may cause Android Studio to add necessary
+  dependencies and permissions to your app. Each configuration page lists these
+  and other actions that Android Studio takes if you enable the associated service.
+</p>
+
+<h2 id="modules">
+  Modules
+</h2>
+
+<p>
+  The <em>Modules</em> settings section lets you change configuration
+  options for each of your project's modules. This section contains one page
+  for each module in your app. In many cases, the project has just a single
+  module, named <em>app</em>. However, if your project targets multiple form
+  factors, it might have several modules. For example, if your project contains
+  both a tablet app and a wearable app, it might have two modules, named
+  <em>mobile</em> and <em>wear</em>. For more information about project
+  modules, see <a href=
+  "{@docRoot}tools/projects/index.html#ApplicationModules">Android Application
+  Modules</a>.
+</p>
+
+<p>
+  Each module's settings page is divided into the following panes:
+</p>
+
+<ul>
+  <li>
+    <strong>Properties:</strong> Specifies the versions of the SDK and build
+    tools to use to compile the module.
+  </li>
+
+  <li>
+    <strong>Signing:</strong> Specifies the certificate to use to
+    <a href="{@docRoot}tools/publishing/app-signing.html#sign-auto">sign your
+    APK</a>.
+  </li>
+
+  <li>
+    <strong>Flavors:</strong> Lets you create multiple build <em>flavors</em>, where
+    each flavor specifies a set of configuration settings, such as the
+    module's minimum and target SDK version, and the
+    <a href="{@docRoot}tools/publishing/versioning.html">version code and
+    version name</a>. For example, you might define one flavor that has a
+    minimum SDK of 15 and a target SDK of 21, and another flavor that has a
+    minimum SDK of 19 and a target SDK of 23.
+  </li>
+
+  <li>
+    <strong>Build Types:</strong> Lets you create and modify build
+    configurations, as described in <a href=
+    "{@docRoot}tools/building/configuring-gradle.html">Configuring Gradle
+    Builds</a>. By default, every module has <em>debug</em> and
+    <em>release</em> build types, but you can define more as needed.
+  </li>
+
+  <li>
+    <strong>Dependencies:</strong> Lists the library, file, and module
+    dependencies for this module. You can add, modify, and delete dependencies
+    from this pane. For more information about module dependencies, see
+    <a href="{@docRoot}tools/building/configuring-gradle.html#declareDeps">Declare
+    dependencies</a> in <a href=
+    "{@docRoot}tools/building/configuring-gradle.html">Configuring Gradle
+    Builds</a>.
+  </li>
+</ul>
