+Plugin Development
+==================
+
+Note: The plugin API is **considered alpha** at the moment.
+
+Plugins are useful to extend the core functionalities of Kanboard, adding features, creating themes or changing the default behavior.
+
+Plugin creators should specify explicitly the compatible versions of Kanboard. Internal code of Kanboard may change over time and your plugin must be tested with new versions. Always check the [ChangeLog](https://github.com/kanboard/kanboard/blob/master/ChangeLog) for breaking changes.
