How to install ckEditor?

I'm trying to install ckEditor. I already ran the following script:

composer require ckeditor/ckeditor

How do I know if ckEditor is installed?

How do I implement ckEditor to my textarea:

{!! Form::textarea('body', null, ['class' => 'form-control']) !!}

Does this install automatically sets up the permission for Laravel, so the user can upload images through ckEditor?
