# Required Experience Required technology knowledge. The IntelliJ Platform is a JVM application, implemented mostly in [Java](https://www.oracle.com/java/) and [Kotlin](https://kotlinlang.org). At this time, it's not possible to develop plugins for the IntelliJ Platform in non-JVM languages). Developing a plugin for the IntelliJ Platform requires knowledge and experience with the following technologies and concepts: - Java, Kotlin, or any other JVM language, and its standard and third-party libraries - [Gradle](https://gradle.org/) or a similar build system (for example, Maven) - [Swing](https://en.wikipedia.org/wiki/Swing_(Java)) for building user interfaces - [Java Concurrency Model](https://docs.oracle.com/javase/tutorial/essential/concurrency/index.html) - experience with IntelliJ Platform-based IDE (for example, [IntelliJ IDEA](https://www.jetbrains.com/idea/)) Keep in mind that the IntelliJ Platform is a large project, and while we are doing our best to cover as many topics as possible, it is not possible to include every feature and use-case in the documentation. Developing a plugin will sometimes require digging into the [IntelliJ Platform code](https://github.com/JetBrains/intellij-community) and analyzing the [example implementations in other plugins](https://jb.gg/ipe). > It is highly recommended to get familiar with the [](explore_api.md) section before starting with the plugin implementation.
