Hi @adiati98! :) I closed this issue because you mention wanting to make these changes in the guestbook repo, not the intro repo.

Hey @CBID2 I opened this issue because I will move the content from the guestbook repo to this repo, as I mentioned in the description and proposed solution. Thus, I'm working on both guestbook and intro repos.

I would appreciate it if you could reopen this issue as a reference to my future PR because I can't do so from my mobile app. Thank you 🙂

It's reopened @adiati98. Do you mind if I do the changes you suggested for the guestbook repo? I've been wanting to update the documentation there, and you inspired me a bit. 😁

Thanks for reopening, @CBID2 ! 😊

I will move those sections entirely from the guestbook to the intro course, so it would be less confusing for me if I could do it by myself altogether as they are related.

It would be great if you could wait for my PRs to be merged, and you can propose your ideas in a new issue. 😉
