When delete and skip are the only Rule types available, this indicates that only one root path was entered into the 'Root Paths' panel of the Job wizard. This panel should have all root paths, both source and all destination paths, listed. Later in the wizard you will be presented with a panel that lets you select which paths are source and destination.
Once two or more paths are listed (the source and one destination) all of the available synchronization rules will be available for you to select.
