What is repo?

A repo is like a special box where people keep their work so others can use it or add to it.

Imagine you and your friend are building a sandcastle at the beach. You both want to make it bigger, but you need to know what each of you has already added. So you put all your parts in a box, that's like a repo. When your friend wants to help, they can look inside the box and see what you've done, then add their own stuff too.

A repo is like a shared notebook for everyone working on the same project. You write or draw in it, and others can read from it or add new pages, all at the same time. This helps people work together even if they are not in the same place.

People use repos because they make teamwork easier, like having one big shared table where everyone can put their toys and take turns playing with them.
