Quick Start

This tutorial on writing extensions gives you a hands-on introduction to
the Plesk extensions SDK. Starting from specially-prepared code, it
guides you through the process of developing a typical extension with
the GUI, a simple news feed reader, and, finally, the extension which
displays usage statistics.

Each exercise consists of several steps. You should follow the steps to
gradually create and refine your extension. The exercises explain each
step in detail and provide all the sample code you need to complete the
extension.

After you complete the tutorial, you will learn many of the most
important concepts in extensions development. If you want to add more
complex features to your extensions, examine the extensions SDK
reference.

Preparing for the Exercises

To prepare for the exercises, browse our GitHub
page. You should see six
subdirectories: ex1, ex2, ex3, ex1complete, ex2complete, and
ex3complete. The ex# directories are the starting points for each of
the exercises, while the ex#complete directories are completed
exercises. If you are having trouble with a particular exercise, you can
compare your current work against the completed variant.

Unless otherwise stated, directory paths in the following exercises are
given relatively to the root directory of an extension (which is the
contents of ex# or ex#complete).

Exercises

The table below lists the tutorial exercises and describes the
development areas that each covers. Exercises do not depend on each
other; you can complete them in an arbitrary order.
