In this intro episode, we kick things off by taking a look at the full-featured comment system we'll be building together. You'll see how comments can be attached to any model—whether that's an article, a course, or anything else in your app. The idea is to make a reusable component: drop it in anywhere, pass in your model, and it's ready to go.

We walk through posting a comment, editing it, deleting, and replying (including nested replies, which are capped at one level to keep things simple but can be adjusted later). Although the demo's a bit rough right now (no fancy avatars and the date formatting needs some love), we talk about how these details will be cleaned up as we go through the course.

Permissions are covered too—you'll only be able to edit or delete your own comments, and we'll see how to handle that properly. So by the end of the series, you'll have a comment system that's super easy to integrate and extend for just about any use case.
