A comment section is a great way for your users to interact with content.
Comments can be tricky to implement, as there are a number of considerations in how they will work. For example, they can be linear or threaded. They can have additional features like voting or other responses.
If you have a closed site with known users, moderation is less of a problem. But if it's open to the public, you may need a lot of protection from spammers.
Consider a service like Discus that can manage comment accounts for you.
