Git & GitHub For Beginners - Master Git and GitHub (2025)

Download and install git on your operating system, launch git bash, verify the installation with git --version (expect 2.27 on Windows), and use git help to access command guidance.

Configure git global user name and email with git config to attribute changes and identify who made each update in your projects.

Create your first git project by initializing a repository in a new folder with git init. Use git bash to navigate directories and verify setup with git status on master.

Master the basic Git workflow by creating files, staging them, and committing changes. Track the three areas: working directory, staging area, and repository, and review history with status and log.

Learn basic Git and version control by creating and tracking files, staging changes, and committing with descriptive messages, then compare snapshots and revert to previous versions.

Master git diff to review changes by comparing your working directory with the last commit, explore differences between commits, and inspect diff variations across the staging area and repository.

Learn how to remove files and directories from a git repository using git rm, including removing multiple files and using the -r option for directories.

Learn how to use git tags to mark important points in a repository's history, including lightweight and annotated tags, creating and listing tags, searching by name, and deleting tags.

Unstage a mistakenly staged file by using git restore --staged <file> to move it back to the working directory, or use git reset -- <file> in older workflows.

Use git restore to revert a file back to its state in the last commit from your working directory, and learn when this approach is appropriate and the risks.

Explore why a remote version control system is essential for collaboration, enabling the management of a shared repository and coordinated work on your project. See how this complements local workflows.

Explore how remote and cloud-based repositories enable team collaboration, allowing you to push and pull changes, view teammates' work, and maintain an online backup of your project.

Choose GitHub as the remote version control hosting service, acknowledging its global developer community and vast repositories, and create a new account to start working with GitHub.

Create a GitHub account by filling signup form, choosing a username, and entering your email and password. Verify your email, complete setup, and sign in to explore home page.

Explore GitHub to discover and create repositories, switch between private and public options, and navigate topics, trending projects, and collaborations to find interesting work.

Learn how to create a GitHub repository, choose public or private, optionally add a readme, license, and gitignore, and push a local project to collaborate with others.

Learn to push a local git repository to a remote GitHub repository by configuring origin, verifying the remote, and running git push origin master.

Push, fetch, and work with a private remote on GitHub, not just public repositories, and learn how to switch visibility between private and public, including ssl keys and transferring files.

Master the ssh process to secure remote connections using a public/private key pair, enabling authentication with GitHub or GitLab via ssh-keygen and rsa/dsa algorithms, and placing keys in authorized_keys.

Learn how the watch and star features on GitHub work, with watch notifying you of all changes to a repository and star bookmarking projects without notifications.

learn to use the raw view to copy the raw source code, and use blame and history to see who wrote each line and track file commits.

Explore how GitHub issues function as a project tracker, turning to-do items into labeled issues using labels, milestones, assignees, descriptions, and comments for effective collaboration.

Discover how to use a .gitignore file to exclude build directories, temporary files, and non-source files from your repository, and leverage GitHub's recommended templates.

Learn how forking on GitHub creates your own copy of a repository, enabling you to commit changes and propose improvements via pull requests.

Learn to clone a repository from GitHub to your local machine, distinguish fork from clone, and push changes via git add, commit, and a pull request.

Understand branches as safe development paths that keep the master branch stable, enabling experiments, feature work, and bug fixes, then merge changes after review.

Learn to create and switch branches, commit changes, and push a descriptive greetings branch to GitHub, while keeping production on master and testing new features like moon flight.

Explore extended visualization of git concepts, seeing how files move with git commands to deepen understanding and build the confidence to start working with git.

Visualize git's local workflow by exploring untracked, tracked, changed, staged (index), and committed states. Understand the working directory versus the .git directory and core state transitions.

Learn how untracked files behave in your working directory and how git tracks changes. Use git status to distinguish untracked from tracked files and understand when to add them.

Learn how to track new files with git add, moving them from untracked to staged, and verify changes with git status; includes tracking directories recursively.

Discover how git tracks files from unmodified to modified and staging states, and how git add moves changes into the staging area for the next commit.

Discover how a file can exist in both staged and working directory states before a commit. See how git status and git add manage these changes to define next snapshot.

Commit staged changes to the repository with git commit -m, creating a snapshot of the staging area and revealing the branch and files changed.

Skip the staging area by using git commit -a to stage and commit tracked changes in one line, then learn when to use it and potential caveats.

Explore real life branching strategies in git, including master, feature, and issue branches, and learn how to merge changes while avoiding conflicts and keeping production stable.

Explore how to merge feature and issue branches into the master branch using the fast-forward technique, including checking out branches, performing the merge, and deleting obsolete branches.

Explore recursive three-way merging, see how the feature and master branches converge into a single merge commit, and learn to update the feature branch before finalizing the merge.

View a practical, real-time demonstration of merge conflicts when two branches modify the same file, including conflict markers and the steps to resolve so the merge can continue.

Learn to resolve git merge conflicts, from pending local changes to merge failures. Inspect status, edit conflicted files, and commit the resolved merge.

Use git status --short to quickly summarize repository changes with a concise output. The dash s flag reveals untracked, modified, and staged files with clear indicators.

Learn to use git log to view repository history in reverse chronological order with author and email, and message details, and explore diffs via patch options and time-based filters.

Discover how to create and use git aliases to shorten daily commands, improve readability, and customize workflows with examples like status, commit, and last.

Learn how to remove files in git, including deleting from the working directory and staging the deletion with git add or using git rm, plus ignore with gitignore.

Move and rename files in Git efficiently with git mv, avoiding manual rm/add workflows and ensuring changes are staged and committed.

Discover GitLab as a web-based devops tool that hosts Git repositories with wiki and issue tracking, and learn to sign up, start a free trial, and create your first project.

Create your first GitLab project within your group to house the repository, issues, and documentation, then explore importing from GitHub or Bitbucket and the starter sandbox project.

Explore GitLab basics by navigating issues and boards and viewing open or closed items. Set up your profile and status, and learn to use labels, milestones, and deadlines in issues.

Start working with a GitLab project by cloning or initializing a repository and adding a Readme.md. Push changes, configure a remote origin, and note the SSH key requirement.
