How to use gitlab CI/CD so that it any changes on master branch will automatically reflect on live site

Hello All,

I wanted to implement something like scenario explained below-

I have one repository on gitlab, and i wanted to use master branch codes to my site somewhere hosted on cpanel. So that any changes on master branch will directly reflect on my live hosted site.

I read somewhere that this could be implemented with the help of gitlab CI/CD but when i go though the documentation, i didn't understand anything.

Can anyone suggest me any short article or documentation which will help me to understand gitlab CI/CD documentation?

Thanks in advance :)
