The article was so good, it was very informative, But I can’t add a comment on the blog.

Hello enzo,

Thanks for the feedback.

The comment system (Coral Project Talk) requires a simple registration (login with social logins)

1. Click the load comment button

3. Choose the external user login system
   It supports Google
   For GitHub/GitLab, select the other social logins
   The Coral product has a bug for this small window, you should be able to scroll down to see the other item for other social logins

4. For other social logins, resize this window (this part is from Auth0)
   and you should see GitHub or GitLab social login

It is a bit complicated because I wanted authenticated user to comment (or delete their own comment because of GDPR). Also the Coral Talk comment system could integrate with external systems for spam checking or harmful messages.
