Click the Add Announcement button.
Type a title for the announcement in the topic title field  and add content in the Rich Content Editor . You can also add links, files, and images to the announcement using the content selector .

You can add an attachment to your announcement by clicking the Choose File button .

You can also enable an announcement podcast feed  and allow students to like announcement replies .
Click the Save button.
