+#### Customizing the recipient
+
+Slack is fairly flexible, which allows us to override the custom webhook's channel by using the `to` method. This method accepts both `#channel` and `@username` notation. The latter will send the notification to a specific user.
+
+    /**
+     * Get the Slack representation of the notification.
+     *
+     * @param  mixed  $notifiable
+     * @return SlackMessage
+     */

+                    ->content('This will be posted in #laravel-other')
+    }

+#### Customizing the bot's username and icon
+
+By default, the incoming webhook will use the default identity that you have configured in Slack, but with the `from` method it's trivial to set a custom username and icon:

+    /**
+     * Get the Slack representation of the notification.
+     *
+     * @param  mixed  $notifiable
