Perhaps the most powerful application of PyQGIS is the ability to turn your scripts into plugins that can be shared with the entire QGIS community. The "PyQGIS Programmer’s Guide" dedicates entire chapters to this, showing you how to package your code, create a user interface, and distribute your plugin via the official QGIS Plugin Repository.

The guide covers the following basic concepts:
