The Update from ScreenSteps option reimports the instructional content from ScreenSteps.
This option is useful if after importing, you go back to ScreenSteps and make changes to the manual. The option serves as a shortcut to reimport and thus keeps your ScreenSteps manual and Content Engine import in sync.
You can refer to the sample ScreenSteps manual to see the various formatting tags for the lab manual, and its rendition in the VMware Lab Platform user interface.
