Learn how to build plugins using IntelliJ Platform SDK for the [JetBrains products][jb:products] by experimenting with our code samples.
These samples show you how features work and help you jumpstart your plugins.

> [!TIP]
> To start a new plugin project, consider using [IntelliJ Platform Plugin Template][gh:template] which offers a pure boilerplate template to make it easier to create a new plugin project.
>
> The code samples can also be found in the [IntelliJ SDK Code Samples](https://github.com/JetBrains/intellij-sdk-code-samples) mirror repository.

To learn more, browse [available Extension Points][docs:eps], explore Extension Point usages in open-source plugins using [IntelliJ Platform Explorer](https://jb.gg/ipe) and learn how to [Explore the IntelliJ Platform API][docs:explore-api].

## Target Platform

All Code Samples target the latest GA platform release.
Previous releases are made available via [tags](https://github.com/JetBrains/intellij-sdk-code-samples/tags).

## Structure

Code Samples depend on the [IntelliJ Platform SDK][docs] and [Gradle][docs:gradle] as a build system.

The main plugin definition file is stored in the `plugin.xml` file, which is created according to the [Plugin Configuration File documentation][docs:plugin.xml].
It describes definitions of the actions, extensions, or listeners provided by the plugin.

## Code Samples

Please see [Code Samples][docs:code-samples] topic on how to import and run code samples.

In the following table, you may find all available samples provided in the separated directories as stand-alone projects available for running with the Gradle [`runIde`](tools_gradle_intellij_plugin.md#tasks-runide) task.
