+<excerpt>Alternative strategies and tools to avoid building a "full" plugin.</excerpt>
+
 In some cases, implementing an actual IntelliJ Platform plugin can be overkill, and using one of the alternative approaches listed below may provide you with the required value in a much shorter time.
 If you need a functionality that is specific to your project domain, conventions, or practices, you can avoid all the steps that are required to implement and publish a plugin and provide these features as a part of your project or IDE configuration files.

 This guide is split into several parts, similar to a textbook.
 Each one builds on the content of the previous section, but it is not necessary to read the guide in order.
 The [Key Topics](key_topics.md) page aims to link to the pages that are necessary to be able to understand the architecture and get started building plugins.

+<excerpt>Introduction to the IntelliJ Platform, plugins, and IDEs based on it.</excerpt>

 The IntelliJ Platform is not a product in and of itself but provides a platform for building IDEs.
 It is used to power JetBrains products such as [IntelliJ IDEA](https://www.jetbrains.com/idea/).
 It is also Open Source and can be used by third parties to build IDEs, such as [Android Studio](https://developer.android.com/studio/index.html) from Google.
