Built in slug vs unique url?

Questions
1

I am confused about how to create an url for a user-submitted article. I can across some documentation that says you can set the slug to be the url, but in my database it says the slug is “built-in.” Does that mean the url is automatically created? Using what info? Ideally, the url would be something like: site + username + article title

Ultimately, I want readers to browse a list of articles (currently set up with a repeating group), click on one, and then be directed to a single page containing that article. That reminds me of a second question: do I have to add a page for each url? Or is there a way to set it so that each url automatically has a dedicated page following a universal layout (ex. title, author, picture, content, comments at bottom, etc)

You can set a thing’s slug to whatever you like (as long as it’s unique… and if it’s not then Bubble will take care of that by appending a number to the end automatically)

Thanks. I figured out how to send the data from a cell in my repeating group to another page and it configures the url based on the title.
