You don't have to do each step separately first, but if you don't give the 
right leadin, you won't even see the help options.  E.g., if you type

dism  /?

then "/cleanup-image" will not be one of the options listed.  "/online" 
will be listed, and you have to know to ask for 

dism /online /?

and then "/cleanup-image" will be be listed.  If you want to discover 
"/checkhealth ", "/scanhealth", or "restorehealth" you have to include 
"/cleanup-image":

dism /online /cleanup-image  /?
