How do I get my website Duelingpets to display instead of the exampe site?

I am trying to rebuild my website Duelingpets using the new Ruby on Rails 5.2 Engine. I used the one build app for rails setup. I logged in using the default user environment that rails setup. I created a folder called Duelingpets and placed it next to the example folder. I disabled the main service on rails and changed the sites-available section to point to the Duelingpets folder, but it still points to the example folder even though I changed it.

I am following a bit of this article but I don’t understand it completely. https://www.digitalocean.com/community/questions/why-can-i-only-view-default-yay-you-re-on-rails-page

I don’t know where I went wrong with this, but I could use some help in getting this program setup. I am very unfamiliar with this process as I only implemented the Ruby on Rails 3.2.14 engine prior. So I am not familiar with all of the new technology that Rails 5.2 does. Any advice on how I can get it to display the default sessions file I created?
