+## Extending
+
+**For the purpose of this section, we will use `editor-js/warning` as an example of extensibility.**
+
+There are two steps to extending the editor. The first consists of creating a JavaScript file and passing it onto Nova.
+The second step allows you to create a blade view file and pass it to the field to allow your block to render in the Nova `show` page.
+
+### Creating the Javascript file
+
+`resources/js/editor-js-plugins/warning.js`
+
+```js
+/*
+ * The editorConfig variable is used by you to add your tools,
+ * or any additional configuration you might want to add to the editor.
+ *
+ * The fieldConfig variable is the VueJS field exposed to you. You may
+ * fetch any value that is contained in your laravel config file from there.
+ */
+NovaEditorJS.booting(function (editorConfig, fieldConfig) {
+ if (fieldConfig.toolSettings.warning.activated === true) {
+ editorConfig.tools.warning = {
+ class: require('@editorjs/warning'),
+ shortcut: fieldConfig.toolSettings.warning.shortcut,
+ config: {
+ titlePlaceholder: fieldConfig.toolSettings.warning.titlePlaceholder,
+ messagePlaceholder: fieldConfig.toolSettings.warning.messagePlaceholder,
+ },
+ }
+ }
+});
+```
+
+`webpack.mix.js`
+
+```js
+const mix = require('laravel-mix');
+
+mix.js('resources/js/editor-js-plugins/warning.js', 'public/js/editor-js-plugins/warning.js');
+```
+
+`app/Providers/NovaServiceProvider.php`
+
+```php
+// ...
+public function boot()
+{
+ parent::boot();
+
+ Nova::serving(function () {
+ Nova::script('editor-js-warning', public_path('js/editor-js-plugins/warning.js'));
+ });
+}
+// ...
+```
+
+`config/nova-editor-js.php`
+
+```php
+return [
+ // ...
+ 'toolSettings' => [
+ 'warning' => [
+ 'activated' => true,
+ 'titlePlaceholder' => 'Title',
+ 'messagePlaceholder' => 'Message',
+ 'shortcut' => 'CMD+SHIFT+L'
+ ],
+ ]
+ // ...
+];
+```
+
+### Creating the blade view file
+
+`resources/views/editorjs/warning.blade.php`
+
+*CSS classes taken from [here](https://github.com/editor-js/warning/blob/master/src/index.css).*
+
+```html
+
+
+
{{ $title }}
+
{{ $message }}
+
+
