Module 3: Collaboration and Teamwork

Move into professional team development concepts. * Creating and switching branches * Merging code and resolving merge conflicts * Forking open-source repositories * Opening, reviewing, and merging Pull Requests * Using Issues and Discussions

Module 4: Advanced Fixes and Practice

Learn to undo mistakes and apply your knowledge. * Restoring files and resetting commits * Stashing temporary work * Fixing the "Non-Fast-Forward" error * Daily developer and team collaboration workflows * Hands-on beginner and intermediate coding tasks

Who Is This Repository For?

This repository is useful for:

• Students starting software engineering
• Beginners learning version control for the first time
• Teachers or mentors preparing basic Git sessions
• Developers who want quick revision notes and cheatsheets
• Contributors who want to improve student-friendly learning resources

How to Use This Repository

You can use this repository in three ways:

1. Learn Step by Step

Clone the repository and read through the modules in numerical order (01 to 10).

2. Use as a Cheatsheet

Search inside the notes or open [CHEATSHEET.md](./CHEATSHEET.md) whenever you need to revise a specific command, syntax, or concept.

3. Practice With Tasks

Use the theory questions, checklists, and mini-project from the [10-practice](./10-practice) folder to test your understanding.

Suggested Practice Project

After completing the notes, try building a dummy project by:

• Creating a new empty repository on GitHub
• Cloning it locally
• Adding a README.md and committing it
• Creating a new branch named feature-update
• Making a change, committing, and pushing the branch
• Opening a Pull Request on GitHub and merging it
• Pulling the changes back down to your local main branch
