Add YouTube to your CKEditor

So here is the link.  You download the zip file from ckEditor

https://ckeditor.com/cke4/addon/youtube

You extract that zip file in

PF.Site/Apps/core-CKEditor/assets/ckeditor/plugins/

There are three folders (ckeditor, ckeditor_basic and ckeditor_full) but I put it in the ckeditor folder as shown in the above URL.

Then you go to

PF.Site/Apps/core-CK-Editor/assets/ckeditor/config.js

and add at the end of line 39 youtube like this:

config.extraPlugins = 'youtube';

Refresh the cache and your done.

If you already have added extra plugins like I did you have to add it to the current line. Remember you will need to corresponding plugin folders.  My extra plugins that I already had installed are justify, font, colorbutton, panelbutton and required floatpanel and the newest one youtube.  These were all individual folders download from ckeditor site and put in PF.Site/Apps/core-CKEditor/assets/ckeditor/plugins/.

config.extraPlugins = 'justify,font,colorbutton,panelbutton,floatpanel,youtube';

Here is an image of a successful install of the config.js file.
