The Story of This Book

The general head of the project for creating the free programming book for beginners with an open-source code is Dr. Svetlin Nakov. He is the main ideologist and author of the learning content of the free training course "Programming Basics" in SoftUni, which was used as the basis of the book.

Everything started with the mass free basic programming courses that have been conducted in the whole country since 2014, when the "SoftUni" initiative was launched. At the beginning these courses had larger range and covered more theory, but in 2016 Dr. Svetlin Nakov completely revised, updated and simplified the whole method of teaching, strongly emphasizing on practice. This is how the core of the learning content of this book was created.

The free courses at SoftUni for a start in programming, are probably the most massive trainings ever conducted in South-Eastern Europe. Until 2017 the course in programming basics was held over 150 times, in around 40 Bulgarian towns and cities in person and multiple times online with over 50 000 participants. It was completely natural to write a book for the tens of thousands of participants at the SoftUni basic programming course.

Following the principle of free software and free knowledge, Svetlin Nakov led a team of volunteers and started this open-source project. At first the idea was to create a free book with the basics of programming with the C# programming language and then other similar books with other programming languages (like Java, JavaScript and Python).

The book was initially written in Bulgarian language in 2017 and later translated into English in 2019.

The project is part of the hard work of the Software University Foundation to create and distribute an open learning content to teach software engineers and IT professionals.
