Quick start

CKEditor 5 online builder

The easiest way to start using CKEditor 5 with all the features you need is to prepare a customized build with the online builder. All you need to do is choose the preferred predefined build as a base, add all the required plugins, and download the ready-to-use package. Refer to the Online builder Quick start guide to follow this installation path.

CKEditor 5 predefined builds

CKEditor 5 predefined builds are a set of ready-to-use rich text editors. Every build provides a single type of editor with a set of features and a default configuration.

The following CKEditor 5 predefined builds are currently available:

• Classic editor
• Inline editor
• Balloon editor
• Balloon block editor
• Document editor

Example installation

Creating an editor using a CKEditor 5 build is simple and can be described in two steps:

1. Load the desired editor via the <script> tag.
2. Call the static create() method to create the editor.

In your HTML page, add an element that CKEditor should replace:

<div id="editor"></div>

Load the classic editor build (you can choose between the CDN, npm, and zip downloads):

<script src="https://cdn.ckeditor.com/ckeditor5/41.2.0/classic/ckeditor.js"></script>

Call the ClassicEditor.create() method:

<script>
	ClassicEditor
		.create( document.querySelector( '#editor' ) )
		.catch( error => {
			console.error( error );
		} );
</script>

You’re ready to go!
