Quick start

CKEditor 5 Builds

CKEditor 5 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 Builds are currently available:

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

Example

Creating an editor using a CKEditor 5 build is very 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:

<textarea name="content" id="editor"></textarea>

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

<script src="https://cdn.ckeditor.com/ckeditor5/<version>/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!

To find out how to start with other builds check the Quick start guide in the CKEditor 5 documentation.

CKEditor 5 Framework

CKEditor 5 Builds allow you to quickly and easily initialize one of the many types of editors in your application. At the same time, CKEditor 5 is also a framework for creating custom-made rich text editing solutions.

To find out how to start building your own editor from scratch go to CKEditor 5 Framework overview section of CKEditor 5 documentation.

Contributing and project organization

Ideas and discussions

The main development repository of CKEditor 5 is located at https://github.com/ckeditor/ckeditor5. This is the best place for bringing opinions and contributions.

Development

CKEditor 5 is a modular, multi-package, multi-repository project. It consists of several packages that create the editing framework, based on which the feature packages are implemented.

The ckeditor5 repository is the place that centralizes the development of CKEditor 5. It bundles different packages into a single place, adding the necessary helper tools for the development workflow, like the builder and the test runner. Basic information on how to set up the development environment can be found in the documentation.

See the official contributors' guide to learn how to contribute your code to the project.
