Git and Version Control for Development Teams

A practical Git course for development teams that need one reliable, shared way of working. Participants learn the Git object model, branching and merging strategies, pull-request review, conflict resolution, history repair, and the repository conventions that keep parallel work safe and traceable.

Overview

Practical learning for workplace transfer.

Most teams learn Git as a list of commands and discover the gaps only during a bad merge, a lost branch, or a release that cannot be traced back to its code. This course rebuilds the mental model first — commits, trees, refs, and the difference between rewriting and reconciling history — then applies it to the situations that actually cost delivery time: long-lived branches, review bottlenecks, hotfixes against a released tag, and recovering work that appears to be gone. Participants leave with a written branching and review convention their team can adopt on the next sprint.

Prerequisites

Comfort with a command line and basic software development experience. No prior Git knowledge is assumed.

Objectives

  • Explain the Git object model and what a commit, tree, ref, and HEAD actually represent.
  • Select a branching strategy that matches the team's release cadence and review capacity.
  • Resolve merge and rebase conflicts without losing work or corrupting shared history.
  • Run pull-request reviews that surface defects early and keep delivery moving.
  • Recover lost commits, branches, and detached work using reflog and recovery commands.
  • Document a repository convention covering naming, commits, tags, and protected branches.

Target audience

  • Software developers and engineers working in shared repositories
  • Technical leads and code reviewers
  • QA, DevOps, and release engineers
  • Data and automation engineers who version code and notebooks
  • Engineering managers standardizing team workflows
  • Teams migrating from centralized version control to Git

Program outline

A clear structure for the learning journey.

Program outline

Outline points are grouped in one designed block instead of being treated as separate module cards.

Module 1: The Git Object Model and Local Workflow

Commits, trees, blobs, refs, and HEAD explained through the actual object store

Working tree, staging area, and commit: what each command really moves

Writing commit messages that survive as release and audit evidence

Inspecting history with log, diff, blame, and bisect

Module 2: Branching Strategies for Real Delivery Schedules

Trunk-based development, GitHub Flow, and release-branch models compared

Matching branch lifetime to review capacity and integration risk

Feature flags as an alternative to long-lived branches

Tagging, versioning, and tracing a release back to its commits

Module 3: Merging, Rebasing, and Conflict Resolution

Merge versus rebase: when each is safe and when it rewrites shared history

Reading a conflict, choosing a resolution, and verifying the result

Interactive rebase for squashing, reordering, and cleaning a branch

Cherry-pick, revert, and reset: choosing the right correction

Module 4: Pull Requests and Code Review Practice

Sizing changes so reviews stay fast and defects stay visible

Review checklists, required approvals, and protected-branch rules

Giving and receiving review feedback without stalling delivery

Automated checks that must pass before a merge is allowed

Module 5: Recovery, History Repair, and Repository Hygiene

Reflog, dangling commits, and recovering work that appears lost

Removing secrets and large files from history safely

Submodules, monorepos, and large-repository performance

gitignore, hooks, and repository configuration standards

Module 6: Team Convention Workshop

Diagnosing the team's current branching and review pain points

Drafting naming, commit, tag, and protection rules

Simulating a hotfix against a released tag under time pressure

Agreeing the convention, its owners, and the adoption steps

Materials provided

  • Course workbook, annotated code samples, and reference notes
  • Hands-on lab environment and starter repositories
  • Exercises, checklists, and reusable code templates
  • 4D Certificate of Completion
  • Post-course technical guidance

Training Options

Programs can be delivered in-house, online, or in a blended format depending on your team's schedule, location, and learning objectives. When an external certificate or exam is included, certification rules and fees remain under the relevant awarding body's policies, while 4D provides the training and preparation support.

Why choose 4D

4D delivers this course against your actual repositories, branching pain points, and release cadence rather than a generic demo project. Trainers work with development, QA, and release stakeholders in the same room, so the convention agreed in the closing workshop is one the whole team can apply on the next sprint.
