I have a gallery which is categorised. The gallery is a Structure section where the user adds an entry and then assigns it to a category - all good.
At the moment, when clicking on an entry title the URL is mysite.com/gallery/entry-slug but I would like it to be mysite.com/gallery/category-name/entry-slug.
I've looked around the Docs and StackExchange for a simple answer (assuming it would just be the addition of a tag) but the solutions seem very convoluted and way outside my grasp of understanding.
Any help appreciated
