This is not true, you are quoting a very old post from 2016
I’ve since renamed both the index page and CMS collection to projects
.
The index page method still can be achieved
I still have both an index page at /projects
and individual CMS items starting with /projects/{slug}
Here are the new URLs since you mentioned them:
Samuel Liew - Projects (page without any folder, with slug “projects”)
Tic-Tac-Toe by samliew (page inside a folder “projects”)
Set Game by samliew (page inside a folder “projects”)
