-## Markdown WYSIWYG and markup editor
-
-MarkdownEditor is a powerful tool for working with Markdown, which combines WYSIWYG and Markup modes. This means that you can create and edit content in a convenient visual mode, as well as have full control over the markup.
-
-The editor supports following formats:
-
-* WYSIWYG
-
-* markup
-
-Click on the gear in the upper right corner to change the mode and see the \`md\` markup.
-
-### Various blocks included
-
-{% cut "Combine different blocks" %}
-
-{% note info "Block for notes, tips, warnings, and alerts" %}
-
-Depending on the content, notes with different titles and formats are used:
-
-* Note: provides additional information.
-* Tip: offers a recommendation.
-* Warning: issues a warning.
-* Alert: indicates a restriction.

-      const value = editor.getValue();
-      onSubmit(value);
-    }
-
