6. What Are Git and GitHub?
Before learning the commands, understand the difference.
What is Git?
Git is a distributed version control system used to track changes in files and source code.
With Git, you can:
- Track code changes
- Create different versions of your project
- Revert unwanted changes
- Create branches
- Merge changes
- Work with other developers
- Maintain project history
What is GitHub?
GitHub is an online platform for hosting and collaborating on Git repositories.
Git and GitHub are not the same thing.
Think of it like this:
Git = Version control tool
GitHub = Online platform for Git repositories and collaboration
7. Why Should Students Learn Git and GitHub?

8. Git & GitHub Roadmap
Here's the roadmap you should follow:
Git Basics ↓ Installation & Configuration ↓ Basic Git Commands ↓ Git Workflow ↓ Commits & History ↓ Branches ↓ Merge & Conflicts ↓ Remote Repositories ↓ GitHub ↓ Pull Requests ↓ Collaboration ↓ GitHub Projects ↓ Advanced Git ↓ Open Source ↓ Git Interview Preparation
9. Stage 1 — Learn Git Basics
Start with these concepts:
- Version control
- Version Control System (VCS)
- Distributed version control
- Repository
- Working directory
- Staging area
- Commit
- Branch
- Merge
- Remote repository
Basic Git Architecture
Working Directory ↓ git add ↓ Staging Area ↓ git commit ↓ Local Repository ↓ git push ↓ Remote Repository (GitHub)
Understanding this workflow is extremely important.
10. Stage 2 — Install and Configure Git
After installing Git, configure your identity:
git config --global user.name "Your Name"
git config --global user.email "your@email.com"
Check your configuration:
git config --list
You should understand why Git needs your name and email before moving ahead.
11. Stage 3 — Essential Git Commands
These commands form the foundation of Git.
Initialize a repository
git init
Check repository status
git status
Add a file
git add filename
Add all files
git add .
Create a commit
git commit -m "Initial commit"
View commit history
git log
Short commit history
git log --oneline
12. Understand the Git Workflow
A typical Git workflow looks like this:
Create / Modify Files ↓ git status ↓ git add ↓ git commit ↓ git push ↓ GitHub
For example:
git status git add . git commit -m "Added login page" git push
You should become comfortable with this workflow before learning advanced Git.
13. Stage 4 — Git Branches
Branches are one of the most important Git concepts.
A branch allows you to work on a separate version of your code without directly modifying the main codebase.
For example:
main │ ├── feature-login │ ├── feature-payment │ └── bug-fix
Create a branch
git branch feature-login
Switch branches
git switch feature-login
Or:
git checkout feature-login
Create and switch to a branch
git switch -c feature-login
List branches
git branch
14. Stage 5 — Merging Branches
After completing work on a branch, you may want to merge it into the main branch.
Example:
git switch main
Then:
git merge feature-login
The basic concept is:
main │ └───────┐ ↓ feature-login │ Development │ ↓ Merge │ ↓ main
15. Git Merge Conflicts
Sometimes two branches modify the same part of a file.
Git may then report a merge conflict.
You should learn:
- Why conflicts happen
- How Git marks conflicts
- How to manually resolve them
- How to stage resolved files
- How to complete the merge
Typical conflict markers look like:
<<<<<<< HEAD Your changes ======= Other branch changes >>>>>>> feature-branch
After fixing the file:
git add .
Then:
git commit
16. Stage 6 — GitHub Basics
After learning local Git, start learning GitHub.
Important concepts include:
- GitHub account
- Repository
- Public repository
- Private repository
- README
- Remote
- Clone
- Push
- Pull
- Fork
- Star
- Watch
17. Connect Git to GitHub
Create a repository on GitHub and connect your local project.
Example:
git remote add origin YOUR_REPOSITORY_URL
Check the remote:
git remote -v
Then push:
git push -u origin main
Now your local project is connected to GitHub.
18. Clone a GitHub Repository
If you want to download an existing repository:
git clone YOUR_REPOSITORY_URL
This creates a local copy of the repository.
19. Pull Changes from GitHub
To download the latest changes:
git pull
This is particularly important when working in a team.
20. Push Your Changes
After making changes:
git add . git commit -m "Updated project" git push
Remember:
git add ↓ git commit ↓ git push
21. Git Fetch vs Git Pull
This is an important interview topic.
git fetch
Downloads information about remote changes without automatically integrating them into your current branch.
git fetch
git pull
Fetches changes and integrates them into your current branch.
git pull
A simple way to remember:
fetch = download information
pull = fetch + integrate
22. Stage 7 — GitHub Pull Requests
Pull Requests, commonly called PRs, are extremely important for collaborative development.
A typical workflow is:
Fork / Clone Repository ↓ Create Branch ↓ Make Changes ↓ Commit ↓ Push ↓ Create Pull Request ↓ Code Review ↓ Merge
You should understand:
- What is a pull request?
- How to create one
- Code review
- Review comments
- Approving changes
- Merging pull requests
- Closing pull requests
23. Stage 8 — GitHub Collaboration
Learn how teams use GitHub.
Important concepts:
- Repository permissions
- Collaborators
- Branches
- Pull requests
- Issues
- Code reviews
- Discussions
- Project boards
- Releases
- Tags
This knowledge is particularly useful for team projects.
24. Stage 9 — Important Git Commands
Once you've learned the basics, learn these commands:
git diff git restore git reset git revert git stash git tag git fetch git remote git show git blame git reflog
Don't just memorize them.
Practice each command in a real repository.
25. Git Reset vs Git Revert
This is an important interview topic.
git reset
Moves the current branch reference and can modify the staging area and working tree depending on the mode.
Example:
git reset HEAD~1
git revert
Creates a new commit that reverses the effect of an earlier commit.
Example:
git revert COMMIT_ID
For collaborative branches, understanding when to use revert instead of rewriting shared history is important.
26. Git Stash
Sometimes you're working on something but need to temporarily switch branches.
You can temporarily save your uncommitted changes using:
git stash
Later:
git stash pop
Useful commands:
git stash list
git stash apply
27. Git Tags and Releases
Tags can be used to mark important versions.
Example:
git tag v1.0.0
Then:
git push origin v1.0.0
Tags are useful for marking releases such as:
v1.0.0 v1.1.0 v2.0.0
28. Stage 10 — Advanced Git
After becoming comfortable with the basics, learn:
- Git rebase
- Interactive rebase
- Cherry-pick
- Detached HEAD
- Reflog
- Squashing commits
- Amend commits
- Tags
- Git hooks
-
.gitignore - Git aliases
- Advanced branching strategies
29. Git Rebase
Rebase is an advanced topic that helps you understand how Git history can be reorganized.
Example:
git rebase main
You should understand the difference between:
merge vs rebase
before using rebase on shared branches.
30. Git Cherry-Pick
Cherry-pick allows you to apply a specific commit from another branch.
Example:
git cherry-pick COMMIT_ID
This is useful when you need one particular change without merging an entire branch.
31. Learn .gitignore
You should know how to prevent unnecessary files from being committed.
Example:
node_modules/ .env *.log dist/ build/
For a project, sensitive files such as API keys and environment variables should not be committed to a public repository.
32. GitHub Profile Optimization
If you're preparing for placements, don't simply create a GitHub account and leave it empty.
Build a professional profile.
Add:
- Profile picture
- Short bio
- Location if desired
- Portfolio link
- LinkedIn link
- Strong README
- Relevant repositories
- Good project descriptions
33. What Projects Should You Put on GitHub?
