Git & GitHub - The Practical Guide

Create folders and files using mkdir and echo, navigate with cd, view content with dir and type, and remove items with del and rmdir to manage a project directory.

Understand how Git turns a plain folder into a working directory, uses commits as snapshots, and organizes changes in the master branch, enabling efficient version tracking.

Understand how the working directory and repository use the staging area (index) and objects folder to create commits and track changes efficiently.

Install git on Windows by downloading the 64-bit installer from git-scm.com, running the installer, and using the command-line with default options, then verify with git --version.

Install git on macOS by using Homebrew; open the terminal, paste the Homebrew installation command, install Git, and verify with git --version.

Discover how git log lists commit IDs, messages, and dates, track changes with git status and add, and switch to previous commits on the master branch with checkout.

Merge the third branch into the master branch using git merge to combine feature commits. Master shows three commits and updated files from the merged branch.

Learn how a detached head occurs when you check out a commit outside a branch, leaving HEAD unattached, and how to return to a branch with git checkout.

Learn to undo commits with git reset, using soft and hard reset to move head back and manage changes in the working directory and staging area.

Detect and fix merge conflicts between master and feature branches using VS Code, compare changes with git diff, and resolve by accepting current, incoming, or both changes, then commit.

Explore how Git cherry-pick selectively applies a single commit from a feature branch to master, illustrated by fixing a typo and adding new files.

Explore how to move from local Git projects to the cloud with GitHub, connect Git and GitHub, and master remote, local, and remote-tracking branches along with upstreams and cloning repositories.

connect your local git repository to a remote GitHub repository, creating a remote named origin, and push your branches and commits to the cloud while learning push and pull workflows.

Push a second commit to the master branch on GitHub, verify the update in history, and learn about upstreams, origin, and token-based credential management with Windows Credential Manager.

Explore how local tracking branches bridge your edits and remote branches on GitHub, using fetch, pull, and push to keep remote updates in sync.

Learn to create a local tracking branch connected to a remote branch using git branch --track, understand local versus remote tracking branches, and synchronize changes with push and pull.

Explore how personal access tokens secure GitHub collaboration, enabling push of commits, and distinguish owner vs collaborator access while managing organization versus personal accounts.

Compare owner and collaborator rights on GitHub, highlighting owner actions, collaborator write access in private repos, limit interactions, and the impossibility of read-only access in personal accounts.

Create a new GitHub organization from your personal account using profile settings and the new organization option. Set the organization name, choose the free plan, and provide a contact email.

Explore forks and pull requests on GitHub, showing how open source contributions create forked repositories, propose changes via pull requests, and enable owner review and merging.

Explore forking a public repository to your personal account, clone and push a new feature, then prepare to merge changes back into the original master branch.

Explore how issues, forks, and pull requests operate on a real open source project, learn to create and close issues, describe reproduction steps, and manage labels and projects.

Clone the public repository with git clone, install dependencies with npm install, and modify App.js to add a cart overlay using components/cart in a React project.

Learn to add a collaborator to a GitHub repository via settings, invite Manuel by username, and enable push and pull without sharing access tokens before merging feature branches into main.

Resolve merge conflicts in git by merging a feature branch into main, choosing changes, and updating code to implement a cart toggle with onClose, plus collaborative workflows.

Fork a public repository to your account, clone it locally, and push changes via a pull request. Manage branches on your fork—main or a separate branch—after installing dependencies with npm.

Implement quantity controls by updating add and remove item logic in cart.js, test with npm start, and push a commit with a pull request to Max.
