Lesson Script: Git and GitHub

Lesson Objective

By the end of this lesson, students will be able to understand the basics of version control systems, articulate the significance of Git and GitHub, and perform fundamental operations in Git including creating a repository, committing changes, and pushing code to GitHub.

Duration

30 Minutes

Introduction to Version Control (5 minutes)

What is Version Control?

Version Control systems are essential tools in software development that help track changes in code over time. They allow multiple developers to collaborate on projects without losing progress or causing conflicts.

Importance of Version Control

Collaboration: Multiple developers can work on the same project concurrently.
Backup: Historical versions of code can be retrieved if necessary.
Branching: Developers can create branches to work on features independently, which can later be merged.

Overview of Git (10 minutes)

What is Git?

Git is an open-source version control system that allows developers to track changes in source code during software development. It was created by Linus Torvalds in 2005 and has become the de-facto system for version control in software engineering.

Key Features of Git

Local Repository: Changes are tracked locally in a repository.
Staging Area: Review and add changes to a staging area before committing.
Branching: Create branches for new features or bug fixes without affecting the main codebase.
Merging: Combine changes from various branches back into the main branch.

Git Terminology

Repository (Repo): A directory that contains your project work.
Commit: A snapshot of changes made to the files.
Branch: A separate line of development.
Merge: The process of combining changes from different branches.

Introduction to GitHub (5 minutes)

What is GitHub?

GitHub is a cloud-based platform that hosts Git repositories. It offers various collaborative features that enhance workflow among developers and teams.

Features of GitHub

Remote Hosting: Store your projects online and access them from anywhere.
Collaboration Tools: Track issues, pull requests, and project management features.
Community: Access to a large community of developers and code repositories for learning and collaboration.

Getting Started with Git and GitHub (10 minutes)

Installing Git

For Windows: Download the installer from git-scm.com and follow the instructions.
For Mac: Git is often pre-installed. Check by running git --version in the terminal.

Creating a New Repository

Initialize a new repository:
```
git init my-project
cd my-project
```
Create a new file:
```
echo "# My Project" >> README.md
```
Check status:
```
git status
```

Committing Changes

Add to staging area:
```
git add README.md
```
Commit changes:
```
git commit -m "Initial commit"
```

Pushing to GitHub

Create a new repository on GitHub.

Link local repository to GitHub:

git remote add origin https://github.com/username/my-project.git

Push code to GitHub:
```
git push -u origin master
```

Conclusion and Q&A (5 minutes)
