How to add Formatting Styles in the content editor?

Hi there,

I’m trying to add Formatting Styles (apply custom styles defined in your theme) in the editor bar when editing a content block. It’s blank at the moment and I’m wondering how I can add the classes I use in my theme to active on parts in the content editor.

I’ve figured it out. The documentation with an old and new guide and the lack of a ‘full file preview’ was a bit confusing to follow but it’s working now.
