Changes Return by a State

Description
Standards Documentation for states with regards to changes.

Suggested Fix
Seems it needs to be clear more. Provide sample output for new, existing and removed
State if the recommendation is to always to perform a diff rather than something different, using the standard salt diff for a hash.
Provide an example of using the salt diff for a hash.

 salt minion reg.read_value HKEY_LOCAL_MACHINE 'SYSTEM\CurrentControlSet\Services\RemoteAccess\Parameters\Something' 'ABC'
minion:
    ----------
    hive:
        HKEY_LOCAL_MACHINE
    key:
        SYSTEM\CurrentControlSet\Services\RemoteAccess\Parameters\Something
    success:
        True
    vdata:
        99
    vname:
        ABC
    vtype:
        REG_DWORD

e.g. Persuado code

   before =  __salt__['module.read_something'] # if it does not exist should be set to empty hash/dict
   make changes
   after = __salt__['module.read_something'] # if it does not exist should be set to empty hash/dict
   changes = dict_diff(before, after)

Start with the Salt states writing documentation at the linked writing.html location and review how changes are currently described. Use the provided reg.present output and read_value example to identify what is missing for new, existing, and removed states, including the proposed hash diff example. Done means the recommendation and expected change output are clear for each case.
