 Dashboard API for clients
 ---------------------------------------
 
-+++++++++++++++++
-Implement the API
-+++++++++++++++++
+To provide more information about your widget through the dashboard API for clients, you can implement
+those additional interfaces:
+
+* IButtonWidget to add buttons to be rendered by the client in the widget
+* IIconWidget to set the widget icon URL
+* IOptionWidget to set additional options
+* IAPIWidget to actually provide the widget content (the item list)
+
++++++++++++++++++++++++++++
+The IButtonWidget interface
++++++++++++++++++++++++++++
+
+
+The IButtonWidget interface adds the **getWidgetButtons** method to provide a list of buttons
+to be displayed by the clients in the widget.
+Those buttons let you define actions that can be triggered from the widget in the clients.
+
+There are 3 types of buttons:
+
+* WidgetButton::TYPE_NEW To let users create new elements in your app
+* WidgetButton::TYPE_MORE To let users see more information
+* WidgetButton::TYPE_SETUP If the widget requires some configuration
+
+.. code-block:: php
+
+	public function getWidgetButtons(string $userId): array {
+		return [
+			new WidgetButton(
+				WidgetButton::TYPE_NEW,
+				'https://somewhere.org',
+				$this->l10n->t('Create new element')
+			),
+			new WidgetButton(
+				WidgetButton::TYPE_MORE,
+				'https://my.nextcloud.org/apps/your-app/',
+				$this->l10n->t('More notifications')
+			),
+			new WidgetButton(
+				WidgetButton::TYPE_SETUP,
+				'https://my.nextcloud.org/apps/settings/user',
+				$this->l10n->t('Configure')
+			),
+		];
+	}
+
++++++++++++++++++++++++++++
+The IIconWidget interface
++++++++++++++++++++++++++++
+
+The IIconWidget interface adds the **getIconUrl** method to provide the URL to the widget icon. In the following example
+it returns the URL to the img/app.svg file in your app.
+
+.. code-block:: php
+
+	public function getIconUrl(): string {
+		return $this->urlGenerator->getAbsoluteURL(
+			$this->urlGenerator->imagePath(Application::APP_ID, 'app.svg')
+		);
+	}
+
++++++++++++++++++++++++++++
+The IOptionWidget interface
++++++++++++++++++++++++++++
+
+The IOptionWidget interface adds the **getWidgetOptions** method to provide additional widget options. It returns
+a WidgetOptions object which only contains the **roundItemIcons** boolean value for now. This tells the clients if
+the widget item icons should be rounded or kept as squares.
+
+.. code-block:: php
+
+	public function getWidgetOptions(): WidgetOptions {
+		return new WidgetOptions(true);
+	}
+
++++++++++++++++++++++++++++
+The IAPIWidget interface

 If you want your widget content to be accessible with the dashboard API for Nextcloud clients,
 it must implement the `OCP\\Dashboard\\IAPIWidget` interface rather than `OCP\\Dashboard\\IWidget`.
