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 the time and your plugin must be tested with new versions.
