 ## Configuring IntelliJ Platform Projects for Android Studio Plugin Development
+
 To create a new Android Studio plugin project, follow the tutorial on the [Getting Started with Gradle](gradle_prerequisites.md) page.
 The tutorial produces a skeleton project suitable to use as a starting point for an Android Studio plugin.
 On the [New Project Configuration Screen](gradle_prerequisites.md#new-project-configuration-screen) of the New Project Wizard tutorial, choose Gradle from the product category pane as described in the tutorial, **not** _Android_.
 Some minor modifications to the skeleton project are needed, as discussed below.

 The version number of Android Studio contains the version of the underlying IntelliJ Platform APIs that were used to build it.

 The particular example in that section discusses configuring a plugin project for PhpStorm, so the details for an Android Studio plugin project are reviewed here.
