The course is divided into 4 mini-courses: 'Methods of Open Source Software Development','Linux for Developers', 'Linux Tools for Developers', and 'Using Git for Distributed Development'. Its completion deadline is 2 months. It was an intense and enriching experience! Throughout the course, I delved deeply into the workings of Linux and the dynamics of Git, expanding my understanding of the world of open source code. Each challenge overcome represented a significant personal achievement, and I am eager to apply this knowledge to practical and collaborative projects. This course has strengthened my desire to contribute even more to the open source development community. I am determined to continue learning and growing in this fascinating universe of free software!</p>
