Informing about the unloading (7,3)

'informing' is the definition.
The definition and answer can be both to do with communicating as well as being present participle verbs.
Maybe you can see a link between them that I don't see?

'about the unloading' is the wordplay.
I cannot really see how this works, but
'about' could be 'of' and 'of' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
