How to create a comment section

I have been trying to create a website and one of the aspects that I want to be as a part of the website is a comment section but I can’t find a useful video or website to help me. If you guys could tell me how to make the comment section right here or if its included in one of the FCC lessons or even send me to another link It would be greatly appreciated.Thank you.

Are you trying to create by your own or you are ok to use 3rd party plugin?
