This stage will ultimately drive your implementations by covering a complete list of the most important technical topics inside jBPM6, which will be discussed and demonstrated in practice.

We will begin with simple examples, and then the examples will gain complexity to reach real-life situations. All the source code used in the examples will be available to download and examine, but not all the lines of code will be explained. The technical sections of this book should be read with the source code available. The main idea is that you see the projects in your favorite IDE to practice just as if you were developing your own projects; this will help you to practice and get used to real development tools, projects, and errors.

This first chapter is focused on the whole conceptual background needed to get you started with jBPM6. Most of the concepts that will be introduced in the next section are related to the BPM discipline. These concepts are essential, and the clearer you understand them, the easier it will be to start with your first projects.
