Hybrid Core extensions

Hybrid Core packages several “extensions” within it. Extensions work the same as features, but are a little different. They are external projects that are developed separately from the framework. They’re simply packaged in for convenience.

Like the framework’s features, extensions are modular PHP scripts that you may optionally add to your theme. You get to decide which ones you want to use.

In the theme setup tutorial, you learned how to register support for framework features/extensions in your theme setup function. Below is a list of the available extensions and a quick snippet of code you can copy and paste into your theme setup function for each.

You’ll notice that extensions don’t have the hybrid-core- prefix. This is not a typo. It’s a way to differentiate them from the core framework features.
