In this lesson, you will learn about something called a 'Pull Request' (PR). This is a very important idea when many people work on the same code. You will write a short explanation of what a Pull Request is and why it's used when people work together on a project.

For this lesson, your job is to write an explanation. There are no computer tests to run for this part. You just need to write a clear paragraph about what a Pull Request is and why people use it when they work on code together.

Now it's time to write your explanation! Your main task is to write one short paragraph.

In this paragraph, you need to explain two things:

1. What is a Pull Request (PR)? Think of it as a way to ask for your changes to be added to the main code.
2. Why do people use Pull Requests when they work together? Think about how it helps everyone check the code and make sure it's good before it's added.

You've written your explanation! Now, read it over.

Ask yourself:

✅ Is it easy to understand what a Pull Request is? ✅ Does it explain why people use Pull Requests when they work together? ✅ Is it in your own words?

If you answered yes to these questions, then you did a great job!
