Git Tag Tutorial 🎯

Welcome to the Git Tag tutorial! In this lesson, we'll explore how to manage specific versions of your projects using Git tags. 📝 Note: Git tags are like bookmarks that allow you to easily return to specific points in your project's history.

What is a Git Tag? 💡 Pro Tip: Think of Git tags as a way to mark important points in your project's timeline.

Creating a Git Tag

To create a Git tag, follow these simple steps:
