This Git Masterclass is designed to help developers and DevOps professionals take their Git skills to the next level. This course assumes that you already are an experienced Git user, and will focus on teaching you the more advanced aspects of Git.

Throughout this course, you will learn how to use Git as a toolbox to manage and collaborate on complex software projects. We will begin by exploring the internals of Git and establish a solid vocabulary. You’ll also learn how to use Git to support advanced collaboration strategies and troubleshooting tactics as well as automating tasks using scripting in Bash and Python. Another topic is how to organize repositories and dependencies. Finally we cover security aspects that apply to all projects, e.g. handling of secrets and preventing tampering with tags.

By the end of this course, you will have a deep understanding of Git’s advanced features and be able to use Git as a powerful tool for managing and collaborating on complex software projects. Whether you’re a seasoned developer or a DevOps professional, this course will provide you with the skills and knowledge you need to take your Git skills to the next level.
