+# Writing a New Zeppelin Plugin
+
+<div id="toc"></div>
+
+## What is Apache Zeppelin Plugin
+
+Apache Zeppelin Plugin can extend the functionality of the Zeppelin zengine. Various extensions can be made to the Zeppelin zengine. For this purpose, an interface must first be implemented in the Zeppelin zengine. The biggest advantage of plugins is the [PluginClassLoader](https://pf4j.org/doc/class-loading.html), which ensures that different versions of the same Java classes do not mix between Zeppelin zengine and the plugins and therefore there are no side effects when running Zeppelin.
+
+## Make your own Zeppelin Plugin
+
+Creating a new plugin is quite simple. Just create a new Maven module and make `zengine-plugins-parent` as parent. Create a class with extends `org.pf4j.Plugin`. Plugins are started during Zeppelin Server Startup.
+You can also create classes, which implements `org.pf4j.ExtensionPoint` in Zeppelin zengine.
+
+Current ExtensionPoints:
+
+ - `InterpreterLauncher`
+ - `NotebookRepo`
+
+Because Zeppelin does nothing magical you can find also more informations in the [official PF4J documentation](https://pf4j.org/).
