Version Control for Beginners: A Comprehensive Git & GitHub Course for DevOps Professionals

About Course

This hands-on course introduces the core concepts of version control, then quickly moves into practical Git and GitHub workflows you can apply to real projects. You will learn how to create repositories, record meaningful snapshots of your work, explore change history, and safely experiment with new ideas using branches instead of copying folders like “final_v3_really_final”.

Explain what version control is and why it is essential for modern software and content projects.
Use basic Git commands to create repositories, stage and commit changes, and push them to GitHub.
Work with branches, merges, and pull requests to collaborate without overwriting each other’s work.
Inspect history, compare versions, and roll back mistakes to earlier states of your project.
