Trying to add a comment section

I want a little “comment” section to build a community around my apps topic. Somewhere where a user can come and ask a question, leave a comment or just encourage other users. I have the idea in my head my can’t figure out exactly how I can accomplish this? Is it a form component I will need or just entering different data entry fields? How can another user reply or like that particular comment?

Yes, a form. Write it to a new sheet called comments. Replies would be the same premise…write them to a new sheet called replies. Include identifiers so you can make the necessary relations. Items have comments…comments have replies
