All new Bb courses open to the Homepage.  This page serves as a "dashboard" or bird's-eye-view for the activity in your course.  You DO NOT need to edit the Homepage or change it.  The modules will automatically change when you add a new announcement, new content, set or set a due date for an assignment.  Students can use the homepage to quickly monitor what's new and what's due!  
Start editing the rest of your course by clicking on the menu area you want to work on. For example, click Announcements to access the Announcement area, and to set up the course announcements.
