Git and Collaboration Refresher
Refreshes core Git collaboration skills, including commits, branching, rebasing, merging, pull requests, conflict resolution, and safe recovery. Learners progress from local history management to a normal team repository workflow involving reviews and coordinated integration.
What you'll be able to do
- Interpret a commit graph to determine commit order, ancestry, branch positions, and the effects of common branch operations.
- Choose appropriately between merging and rebasing while predicting how each operation changes repository history.
- Explain how a pull request moves a reviewed change into a shared branch and identify the key integration decisions in that workflow.
- Resolve a merge conflict by evaluating competing changes, selecting the intended result, and completing the integration safely.
- Use the reflog to locate a displaced commit or branch tip and select a safe recovery action.
Who this is for
This course is for developers who have used Git before and want to refresh the reasoning behind everyday collaboration workflows. It fits learners who can make basic commits but want more confidence with branches, rebases, pull requests, conflicts, and recovery.
What you should already know
- You have used Git to initialize or clone a repository and create, stage, commit, and inspect changes.
- You understand that branches and remote repositories provide separate names or locations for related lines of development.
- You can use a terminal or Git client to run basic repository commands.

Course content
marks each module's capstone lesson.
01History and Branches4 lessons
Learn how Git records project history and how branches provide movable lines of development for organizing and comparing changes.
Course Introduction
Welcome and orientation: review the course path from local history management through branching, integration, collaboration, and safe recovery.
Commit History
Explore how Git stores commits as a linked history and how history views reveal ancestry and change context.
Branching
Learn how branches name lines of development, how they relate to commits, and how switching between them changes the working context.
History and Branch Synthesis
Synthesize commit-history and branching concepts by tracing ancestry, interpreting multiple lines of development, and reasoning about how branch references change.
02Team Integration and Recovery4 lessons
Learn how pull requests coordinate team review, how to resolve integration conflicts, and how Git recovery tools restore lost or misplaced work safely.
Pull Requests
A pull request presents branch changes for discussion, review, and coordinated integration. Learners identify the relationship between the source branch, target branch, review feedback, and the resulting repository history.
Conflict Resolution
A conflict occurs when Git cannot automatically reconcile changes to the same part of a file or related history. Learners distinguish conflict markers from desired content and reason through the sequence of resolving, staging, and completing the operation.
Reflog Recovery
The reflog records updates to local references, including movements that may no longer appear in the visible branch history. Learners use reflog entries to identify recoverable commits and distinguish inspecting, branching from, and resetting to a recovered state.
Integration and Recovery Synthesis
This capstone combines pull request coordination, conflict resolution, and reflog-based recovery in a single repository-history analysis. Learners determine how to integrate reviewed changes, recover safely from an incorrect reference update, and verify the final branch relationships.
Questions
Is this course suitable if I have never used Git?
It is designed as a refresher rather than a first introduction. You should already be able to create and inspect basic commits; the course focuses on history, branching, team integration, conflicts, and recovery.
Will I learn both merging and rebasing?
Yes. You will analyze how branches and commit ancestry change under common branch operations, then use that understanding to reason about merging and rebasing in team workflows.
Does the course cover pull requests?
Yes. You will interpret how proposed changes are reviewed and integrated into a shared branch, including how pull requests fit into coordinated team integration.
Will I practice resolving conflicts?
Yes. The conflict-resolution lesson focuses on evaluating competing changes, choosing the intended result, and completing the integration safely.
Can this course help if I lose a commit or move a branch by mistake?
Yes. The recovery lesson teaches you to read the reflog, locate a prior reference state, and choose a cautious recovery action for a displaced commit or branch tip.
How does the one-on-one AI tutor fit into the course?
The tutor guides you through each concept, checks your reasoning with focused questions, and adapts explanations when your interpretation of a history, branch operation, conflict, or recovery step is incomplete.
