How to setup a gallery in a post

Hi,
We use WP Bootstrap Carousel plugin which allows you to display the Gallery Post Format. You should install the WP Bootstrap Carousel plugin before getting started. After installing and activating the plugin successfully, you need to insert the shortcode [carousel] into your post. The WP Bootstrap Carousel plugin will get all images which currently uploaded into your Media. So, make sure that you upload images from your computer into the Media Library so that the Gallery Posts will be displayed properly.
Before publishing, navigate to Format pane on right hand side and select Gallery.
Also, you can find here for the document guide on how to configure the theme: http://designwall.com/guide/dw-timeline/
