This plugin comes with a default FOSCKEditorBundle integration. It has also been customized to use image upload feature. Every time you upload an image in the CKEditor, a new image media is being created.
You can use a custom WysiwygType any place you want the CKEditor to appear in. Take the BlockTranslationType as an example.
Note:
In the WYSIWYG fields, you can use Twig function nesting. Read more here.
