This is pretty simple, I found this package: https://github.com/RoumenDamianoff/laravel-sitemap
The Wiki on the Github repo pretty much explains how to setup a sitemap so that you can add one to your project. This is awesome, pretty simple and seems to work well.
Sitemap is probably the number one thing you can do for your site outside of good Meta tags. So really, add this package to your site and start making millions.
