-## Introduction
 Android Studio plugins extend or add functionality to the [Android Studio IDE](https://developer.android.com/studio).
 Plugins can be written in [Kotlin](kotlin.md) or Java, or a mix of both, and are created using IntelliJ IDEA and the [IntelliJ Platform](intellij_platform.md).
 It's also helpful to be familiar with [Java Swing](https://docs.oracle.com/javase/8/javase-clienttechnologies.htm).

-Rider plugins are generally used to expose the functionality of a ReSharper plugin.
+Rider plugins are generally used to expose the functionality of a [ReSharper](https://www.jetbrains.com/resharper/) plugin.
 [Rider](https://www.jetbrains.com/rider/) uses the IntelliJ Platform somewhat [differently](intellij_platform.md#rider) than other Platform-based based IDEs.
 Rider uses the IntelliJ Platform to provide the user interface for a C# and .NET IDE but uses ReSharper to provide the language-specific features.
