Git: The Ultimate Beginner's Guide to Version Control

Master version control with git essentials, from installation and configuration to everyday commands. Collaborate seamlessly with GitHub and apply real-world examples to code projects.

Discover how git functions as a distributed version control system that tracks changes, enables collaboration, and efficiently manages branches, merging, and open source development.

Install git on windows by downloading the 64-bit setup from the official site, run through the installer, finish, and verify with git --version (shows 2.45.2); upgrade if needed.

Configure git with the git config command to set your global username and email for all repositories, or per repository, and verify settings with git config --list.

Learn how the git init command creates a new blank repository by adding a git subdirectory with metadata and a master head pointer, with hands-on steps like cd and mkdir.

Learn how to inspect your repository with git status, identify untracked, modified, and staged changes, and stage files to move them toward the next commit.

Master the git staging area by using git add to stage specific files or all changes with -A or -a, and verify with git status.

Master the git add command to stage and remove files from the staging area, track deletions, and verify changes with git status in a test repository.

Learn how to add files to a new git repository, identify untracked files with git status, stage them with git add, and verify changes staged for commit.

Move from the staging area to a commit, creating checkpoints in git. Always write a meaningful commit message to describe changes, and verify with git status after committing.

Explore git log to view a detailed, chronological history of commits in your repository, including hashes, authors, dates, and messages.

Explore how to use git help to discover commands, view options for git add, and access the full command list to master version control.

Learn to spot changes between git states with git diff, revealing differences across files, branches, and commits. See how unstaged edits appear and decide whether to stage them.

Track changes staged but not committed with git diff using the hyphen staged option to review differences between the last commit and staged changes.

Track changes after committing by staging updates and adding a commit message. Use git log and git diff to compare two commits and visualize changes in the temp1 file.

Learn how Git branches isolate changes to develop features or fix bugs without touching the main branch, then create and manage branches with Git branch and merge back to main.

Master the git checkout command to switch branches. See master and demo as examples, and verify with git branch; an asterisk marks the current branch.

Master git branching, staging, and commits by switching contexts with git checkout, adding and committing changes, and verifying file status across demo and master branches.

Master the merge workflow by combining demo into master with git merge, resolve conflicts manually, and delete branches using git branch -d. Explore fast-forward merges, non-overlapping changes, and identical changes.

Resolve git merge conflicts by applying manual resolution strategies, staging changes, and committing with clear messages. Learn to manage branches, switch between master and demo, and complete merges.

Explore how GitHub extends git with collaboration, social coding, and project management, then create an account and a hello world git repository to start collaborating.

Add and manage remote repositories with git remote add name url, use origin as the default, and push or fetch changes to collaborate efficiently.

Push a local branch to a remote repository and set up tracking with git push --set-upstream origin master, establishing a tracking relationship for streamlined pushes and pulls.

This lecture shows how to fetch updates from a remote repository using git fetch, downloading new branches, tags, and commits without merging. Inspect changes with git log, diff, or show.

Discover how git pull fetches remote changes, downloads updates, and merges them into your current branch, pausing for manual conflict resolution before commit if needed.

Push local changes to the remote repository with git push after staging and committing, then verify status and review the remote branch on GitHub.

Create and manage branches on GitHub to enable collaboration, commit changes to a demo branch from master, and review, compare, and merge pull requests safely.

Pull remote changes into your local branch, resolve conflicts when they arise, and keep master and demo branches synchronized with collaborators on GitHub.

Create and switch to a new local branch, stage and commit changes, then push the branch to GitHub to enable collaboration.

Push the local task branch to the remote repository with git push origin, create a pull request against the master branch, and merge the changes after verification.
