LEARN. PRACTICE. GROW.Git: team decisions and recovery
Practice change selection, branch integration, publication, reversal, and regression diagnosis with Git.
Objectives and progression
A Git workflow path starting with file-state distinctions, progressing to coordinated integration and publication, and ending with recovery and regression investigation. Exercises use fictional repositories and decisions encountered in development and support. Try commands in a disposable repository. This does not award an external certification.
Audience: Developers, DevOps teams, and support engineers working with versioned changes.
Prerequisites: Basic file editing and terminal use; a local exercise repository.

What you will explore
0 / 5Working tree, index, and commit
Distinguish local changes from what the next commit will record.
Branches, merge, and rebase
Choose integration compatible with shared history and resolve conflicts by intent.
Remotes and coordinated publication
Distinguish obtaining history, integrating it, and publishing references.
Reverse changes and preserve work
Choose recovery appropriate to what was saved and shared.
Diagnosis and release traceability
Connect incidents to artifacts and locate relevant changes with evidence.
