Git & GitHub: Build, Collaborate & Automate [2026]

Learn to initialize a local git repository in VS Code with git init, check the git version, and see untracked index.html and style.css, preparing for staging and commits.

Learn how to stage and commit files with git, using git add, git commit, and git status to create an initial commit and track changes in the master branch.

Explore how Git uses commits as snapshots to capture project history, and learn to view, compare, and summarize changes with git log and git log one line, and git diff.

Clone a GitHub repository to create a local copy, modify files, and push changes back, then fork a repository to create a personal copy and submit a pull request.

Learn how to create and switch branches in Git, merge and rebase with fast-forward and no-fast-forward scenarios, and manage conflicts to enable safe, collaborative development.

Master the merge process by combining a feature branch like navbar into main, using git switch, git pull, and git merge with proper origin and push handling.

Explore merging in git, learn how to resolve merge conflicts manually and with ai-assisted tools like GitHub Copilot, and configure Copilot to streamline conflict resolution.

Explore fast-forward and no-fast-forward merges, branching, and merge conflicts in Git and GitHub, with clear history and integration points for team collaboration.

Adopt clear, descriptive branch names using a consistent prefix system (feature, bugfix, hotfix, release, docs) with hyphens and issue IDs from main or master; avoid personal names.

Push and pull code between local and remote repositories using git init, add, and commit, connect to GitHub remotes, and follow practices like pull before push and meaningful commit messages.

Sync local and remote code by fetching updates, merging them, and pushing commits to keep the origin and local branches aligned.

Explore how forks create personal copies on GitHub, how pull requests propose merging changes, and how code reviews ensure quality before merging.

Configure protected branches with GitHub branch protection rules, enforcing pull requests, signed commits, and linear history to safeguard main and master, with feature branch workflows.

Explore ai-powered pull requests with GitHub Copilot, drafting concise PR descriptions, supporting code reviews, and accelerating commits and pushes in modern workflows.

Learn branch naming with prefixes like feature, bug fix, hot fix, release, and docs, and manage multiple remotes with a single command to push to all remotes.

Git stores data as snapshots inside the hidden .git directory, using immutable objects, specifically blobs, trees, and commits, that form a history and enable instant version switching.

Explore commits, blobs, and trees in Git, explained for beginners in the Git & GitHub Masterclass 2025, guiding you from basics to AI-powered proficiency.

Explore how SHA hashes power git by uniquely identifying commits, trees, and blobs with the 40-character SHA1 hash generated from content, creating an addressable database and tamper-proof history.

See how commits work in git, from the staging area and git add to blob and tree objects, the commit, head updates, and the immutable snapshot of history.

Master debugging with Git, tracing issues through commits, SHAs, trees, and blobs; use git bisect to isolate regressions, review logs and diffs, and safely fix and revert changes.

Master git stash and workflows to manage uncommitted changes when switching branches. Learn to save progress with git stash, push messages, apply or pop stashes, list them, and drop stashes.

Learn how to use git rebase to rewrite commit history, placing feature commits on top of main to create a clean, linear timeline free of merge noise for pull requests.

Explore git cherry-pick to apply a single commit from any branch to the current branch without merging, enabling targeted bug fixes and selective feature updates.

Explore how git reflog acts as a time machine, recording every head movement from resets to branch switches, letting you view, recover lost commits, and restore deleted branches.

Create and manage issues in GitHub by adding a title, description, and attachments. Assign labels, milestones, assignees, and projects, then discuss, update, and resolve issues to support collaboration.

Learn how labels, milestones, and assignees organize issues in GitHub, enabling tagging, due dates, assignment ownership, and automated workflows with projects, boards, and the GitHub REST API.

Explore GitHub projects boards with 2025 updates: kanban-style cards, drag-and-drop, inline editing, custom fields, automation, insights, and flexible views like tables, roadmaps, and sprint planning.

Link commits and pull requests to issues using keywords like fixes, closes, or resolves to create automatic links and auto-close issues on merge, while manual linking preserves traceability.

Explore AI-powered issue suggestions and auto-summaries within GitHub Copilot, enabling automatic issue creation, previews, labels, milestones, and collaborative agent workflows.

Compare forking and feature branch workflows to enable secure GitHub collaboration, using forks for open-source contributions and internal branches for team projects, with pull requests to merge changes.

Explore AI-powered development in GitHub Codespaces, where templates and a cloud-based environment accelerate coding, debugging, and real-time collaboration with Copilot-assisted pair programming.

Learn to create and manage GitHub issues, draft a title and description, apply labels and milestones, and organize work with project boards and Copilot-assisted drafting.

Learn how labels, milestones, and assignees organize issues, enable efficient filtering, and scale collaboration with GitHub actions and REST API integrations.

Master data blending by integrating sales and marketing data through CSV uploads, configuring left outer joins, and using blended measures to visualize insights in charts.

Illustrate ai-powered data visualization workflows using Looker Studio and Gemini models to generate insightful charts, box plots, and analytics from structured data.

Learn to set up continuous integration with GitHub Actions by creating a simple ci.yaml workflow file, pushing to master, and validating builds on Ubuntu latest.

Demonstrate automatic deployment of a static website with a GitHub Actions workflow (deploy.yml) to GitHub Pages, including repository setup, adding index.html, and viewing the live site.

Learn how AI-suggested workflows in GitHub Actions guide beginners, automatically creating YAML pipelines, committing changes, and validating builds in dashboards.

Learn how to manage secrets and environment variables securely in GitHub Actions, create and use a workflow, and safeguard private values in a fresh repository.

Explore how GitHub Dependabot and auto security updates automatically monitor your project, identify vulnerabilities, and auto-update dependencies via pull requests, alerts, and continuous security checks.

Explore secret scanning for API keys, passwords, and tokens in repositories, and token protection that enforces permissions and expiration to prevent misuse. Enable these features in GitHub for secure projects.

Explore AI-powered vulnerability alerts in GitHub that automatically detect outdated packages, insecure code patterns, and risky dependencies, flagging issues in the security tab with file and line details.

Learn how code signing with GitHub verified commits ensures authenticity and integrity by using a GPG key to sign commits and verify authors, fostering trust in open source.

Embed SOC2, ISO, and HIPAA compliance into GitHub workflows with branch protection and Dependabot to protect data, enforce security and privacy, control access, and audit changes.

Enforce secure collaboration by implementing team security policies, including security.md reporting, a code of conduct, branch protection, dependency updates, secret scanning, token protection, and code scanning on GitHub.

Learn to implement zero-trust workflows in GitHub by enforcing MFA and SSO, least-privileged access, verified commits, short-lived tokens, continuous monitoring, and automated pre-merge checks.
