The intention of this tutorial is to help you to start developing Extensions in Qlik Sense.

Although at this point it’s important to mention that the main idea behind this tutorial is to bring Qlik Sense’s Visualization Extension concept to everybody, so you don’t need any skills in neither QlikView nor Qlik Sense to get started.
To be able to understand this tutorial, it is not necessary that you have already developed any extensions in either QlikView or Qlik Sense, but you should have a basic understanding of the following concepts:
All the concepts explained in this tutorial certainly work for both Qlik Sense Server and Qlik Sense Desktop. At the same time only Qlik Sense Desktop is necessary to follow the examples in this tutorial.

In addition to Qlik Sense you'll need a code editor, basically every basic editor is sufficient, so something like
All code samples in this tutorial are available on GitHub. At the beginning and end of each chapter you’ll find a short note how to download the corresponding code to a specific chapter.
