Decree a Rodin should be renovated (6)

I believe the answer is:

ordain

I'm a little stuck... Click here to teach me more about this clue!

'decree' is the definition.
(ordaining is a kind of decreeing)

'a rodin should be renovated' is the wordplay.
'a rodin' anagrams to 'ORDAIN'.
But, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for ordain that I've seen before include "Establish" , "Inroad (anag.)" , "Make a decree" , "frock" , "Rule" .)

I've seen this clue in The Sun.
