I figured out part of the process:
To import the data, open the Workbench home page, click Server Administration, then Data Import/ Restore, then locate the cms.sql file, etc.
But I'm still puzzled by Larry's "cms-code" folder. Should I copy and paste the contents to overwrite any existing files in the "Site Shell" that was started on page 34 with yiic?
Also, where can I find the SQL commands? And what should I do with them?
Thanks.
