Mercurial

Mercurial is a type of software that helps people keep track of changes they make to their computer files. Think of it like a big notebook where you can write down everything you do to your drawings, documents, and pictures so you never forget what you did or mess things up by mistake.

When you are working alone, you can easily keep track of everything you do, but when you start working with other people, it can become a bit tricky. If you and your friends all work on the same document at the same time, you may accidentally delete what someone else is doing or overwrite their changes. This is where mercurial comes in handy.

Mercurial helps people keep all of their changes organized and tracked even when they are working together. When you make a change to a file, mercurial will record what you did and give it a name so you can easily find it later. If someone else makes a change to the same file, mercurial will create another name for that change so you can keep track of it too. It's like having little tags on each change so you can remember what happened and who did it!

Mercurial is often used by software developers who are working on big projects with many different people all over the world. They share their code with others and make changes to each other's work, and mercurial helps them keep everything organized and easy to track. Imagine you're playing with your Legos, and your friend is building something with the same blocks. Mercurial is like a grown-up helping you both keep track of your creations and make sure everything stays in its place. In the end, everyone has their own unique structure to be proud of!
