Course 8

Git, GitHub, and Collaborative Development

Practice version history, branches, pull requests, review, conflicts, documentation, licenses, releases, and CI through guided concepts and learner-created local project files. The course combines structured lessons, guided browser concept simulations, and learner-created project files made with freely installable or open tools described in the course instructions. This guided page does not execute code, train models, run databases, create repositories, access hardware, or provide hosted infrastructure.

Free completion promise: The always-free pathway combines branch-and-merge concept simulations with learner-created patch, review, and documentation files. A hosted repository account is optional and is not listed as a paid option.

C4T Git Collaboration Concept Simulator

Free

A free browser concept simulator with adjustable values, a prediction prompt, deterministic feedback, and a short explanatory trace. This guided page does not execute code, train models, run databases, create repositories, access hardware, or provide hosted infrastructure. Use keyboard controls and the text trace or written alternative when a visual or pointer interaction is not suitable.

Open the concept simulator and read its scenario, assumptions, and limitations.

Assignments & capstone

Free tools accepted

Reviewable branch workflow

Create an issue, branch, commits, pull request, and evidence-based review response in the simulator.

The always-free pathway combines branch-and-merge concept simulations with learner-created patch, review, and documentation files. A hosted repository account is optional and is not listed as a paid option. Submit a project file, text trace, screenshots with descriptions, or equivalent simulator evidence.

Conflict, docs, and release repair

Resolve a conflict, improve documentation, select a license, and prepare a tagged changelog.

Final assessment

Safe open-source contribution workflow

Use a learner-created local practice repository and accompanying review files to rehearse an issue, branch, commits, pull request, review response, conflict resolution, documentation update, and automated-check design. Deliverables: Learner-created local repository and review evidence, Readable commit history, Resolved review and conflict evidence, Updated README and license rationale, and Passing automated workflow.
