In each section, click <em>Add block</em> to add a block. You will see a list of the blocks available on your site, plus a section called <em>Content fields</em> with a block for each field on your content item. Each block can be configured, if desired, with a <em>Title</em>, and for content field blocks, you can also configure the field formatter. Continue to add blocks to your sections until all the desired blocks and fields are displayed.
