What's a version control system and how do I get started using one?
A version control system (VCS) is a software tool that helps developers keep track of changes made to their code over time. It allows developers to save different versions of their code, so they can easily go back to a previous version if something goes wrong. It also allows multiple developers to work on the same codebase simultaneously, without overwriting each other's changes.

There are several popular VCSs to choose from, but the most widely used are Git, Mercurial and Subversion.

To get started using a version control system:

1.Choose a VCS (e.g. Git) and install it on your computer.
2.Create a repository for your project. A repository is a place where all the versions of your code are stored.
3.Add the files you want to track to the repository.
4.Make changes to the files, and then commit the changes to the repository. This saves a new version of the code.
5.Repeat steps 3 and 4 as you continue to work on your project.
6.To go back to a previous version of your code, you can checkout that version from the repository.
There are also some web-based platforms like GitHub, GitLab, and Bitbucket that provides a web-based interface for managing git repositories and also provides additional features like code review, issue tracking, and project management.

It's a good idea to start with the basics of VCS and then move on to more advanced features like branching, merging and pull requests. There are a lot of resources available on the internet to help you learn Git, like tutorials, videos, books and more.
Can you explaim it in simpler terms please because its hard to explain that to my colleagues
A VCS is like the version menu in Google Docs, but more advanced. For example, it allows multiple people to work on separate copies of a piece of code, then merge all the changes together.
As your colleagues are new to using VCSes, you might want to show them a GUI to simplify the learning process. Examples include TortoiseSVN, SourceTree, and GitHub Desktop.
