Even though you may jump into any section and start learning, we recommend reading the documentation up with a bunch of pagination configuration. Instead of pulling in the current page, getting a count of db records, and selected your data using a limit/offset just call 'paginate' and tell Laravel Str::singular('users'); Getting the plural form if given value is greater than one: echo Str::plural('comment', count($comments)); Slugs Generating a URL friendly slug: return Str::slug('My First Blog Post!');
