In an attempt to configure CKEditor, I have disabled it from the default Drupal installation. I want to install again. I believe CDN will be easier. How do I accomplish the following task:

To start using CKEditor 4 on your website, add a single

tag to your HTML page:

(http://cdn.ckeditor.com).

If trying to opt for the option of installing on the webhost server,the documentation states:

"Unpack (extract) the downloaded .zip archive to the ckeditor directory in the root of your website."

Does it mean creating a new directory named ckeditor and downloading the extracted files and folders of the zip archive? (snapshot http://drupalaid.blogspot.in/2017/10/blog-post.html).
