+## Documentation
+
+See:
+
+* [Installation](https://ckeditor.com/docs/ckeditor5/latest/installation/getting-started/quick-start.html) for how to install this package and what it contains.
+* [Basic API](https://ckeditor.com/docs/ckeditor5/latest/installation/getting-started/basic-api.html) for how to create an editor and interact with it.
+* [Configuration](https://ckeditor.com/docs/ckeditor5/latest/installation/getting-started/configuration.html) for how to configure the editor.
+* [Creating custom builds](https://ckeditor.com/docs/ckeditor5/latest/installation/getting-started/quick-start.html#building-the-editor-from-source) for how to customize the build (configure and rebuild the editor bundle).
+
+## Quick start
+
+First, install the build from npm:
+
+```bash
+npm install --save @ckeditor/ckeditor5-build-classic
+```
+
+And use it in your website:
+
+```html
+<div id="editor">
+	<p>This is the editor content.</p>
+</div>
+<script src="./node_modules/@ckeditor/ckeditor5-build-classic/build/ckeditor.js"></script>
+<script>
+	ClassicEditor
+		.create( document.querySelector( '#editor' ) )
+		.then( editor => {
+			window.editor = editor;
+		} )
+		.catch( error => {
+			console.error( 'There was a problem initializing the editor.', error );
+		} );
+</script>
+```
+
+Or in your JavaScript application:
+
+```js
+import ClassicEditor from '@ckeditor/ckeditor5-build-classic';
+
+// Or using the CommonJS version:
+// const ClassicEditor = require( '@ckeditor/ckeditor5-build-classic' );
+
+ClassicEditor
+	.create( document.querySelector( '#editor' ) )
+	.then( editor => {
+		window.editor = editor;
+	} )
+	.catch( error => {
+		console.error( 'There was a problem initializing the editor.', error );
+	} );
+```
+
+**Note:** If you are planning to integrate CKEditor 5 deep into your application, it is actually more convenient and recommended to install and import the source modules directly (like it happens in `ckeditor.js`). Read more in the [Advanced setup guide](https://ckeditor.com/docs/ckeditor5/latest/installation/advanced/advanced-setup.html).
