[dennisameling]

We'll need to move the MVC section over from the old docs to the new one. https://developer.mautic.org/#mvc

Hi @dennisameling, @RCheesley. Toyibat from Mautic here! Can I get this issue assigned to me?

I also have a quick question. This section is going to the Plugins section in the new docs, right?

Hi @Teebarh this is from this section: https://developer.mautic.org/#mvc however it needs completely updating because we now use Twig for the front-end. So you'll need to closely review it and in particular we'll need to re-write the views section (and probably much of the other sections) to be sure that the content is relevant for the current setup.

I recommend basing yourself on the 5.2 branch for code and design purposes, but it's worth checking the 6.0 and 7.x branches just to see if anything substantial has changed in those versions, too.
