One code - two ways to add.

The IN3 Framework code can be added to WordPress as a standard plug-in or as an add-on to the theme. We call it by different names: the Plugin Package and the Theme Package, but the code and functionality are the same.

Yes, at first glance, two methods of adding code may seem superfluous, minor, or even complicated during the installation process. However, this is not the case. IN3 Framework can be added, activated, and deleted in a convenient and familiar way, like a regular WordPress plugin. As a result, there are no complications for less-experienced developers when installing. On the other hand, the ability to use IN3 functions as part of the theme allows professional developers to create and transfer one nice package to the end user, which works right out of the box.

Plugin Package
In this package, IN3 Framework is the standard WordPress plugin.
Theme Package
In this package, the IN3 Framework can be included as part of the theme. It installs and updates along with the theme. Ideal for theme developers.
