For my Storyblok setup, I need a minimum of 2 different content types: Portfolio Entries and Blog Entries.
For the portfolio entry, I need the title, slug, image, description, duration, role, and actual content. Luckily Storyblok has a built-in feature for "stories" where it automatically makes a slug when you input the title. You don't need to create neither the title nor the slug yourself.
For the blog entry, I need the title, slug, created date, and the actual content. Same thing here, title and slug are automatic.
And with that, I have the fields I need. Easy as pie.
