Once the blocks are defined you are ready to add items. This can be done in two ways: either click the "Add item" button, which displays a window for browsing the content tree, or use the search interface on the upper left side of the page.

To do a search, enter a search phrase in the Search phrase field and click the orange arrow next to the search field. The results of the search query will be shown beneath the search field. Click the checkboxes beside the items you want to add to the block, then select the block to which they will be added from the drop-down list. When finished, push the "Add to block" button. An example is shown in the screenshot here:

Items are initially added to the Queue. By default, they are scheduled for immediate publication, and will be moved into the Online section when you enable the changes by clicking the "Send for publishing" button. To set a different publication time for an item, enter the number of minutes (from the current time) that the item should be published in the field beside the item in the queue.
