Summary

Over the course of 24 hours, I created a session-based authentication implementation in Mezzio. It was a process that could have been completed far quicker if there was one over-arching authentication tutorial. Specifically, one that brings together all of the relevant libraries into one, comprehensive, easily navigable tutorial, one that steps the user through the process from start to finish.

Ideally, I'd follow the existing format used in existing tutorials, giving a quick introduction/overview, installation of the required packages, then stepping through the respective steps, finishing up with showing a working example, and testing said example.

At the same time we should also make a clean separation:

• Component tutorials
• Mezzio tutorials
• MVC tutorials

Because the current tutorial page with the headline "Components tutorials" is wrong.
Your new tutorial will be added to the Mezzio tutorials.

What do you think?

Sounds good to me! I'm up for that.

Just created #19 for separating the existing tutorials, @froschdesign. Thanks for mentioning that those changes need to be made.
