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.
Perhaps there's an association between them I don't understand?

'about the unloading' is the wordplay.
I cannot really see how this works, but
'about' could be 'of' and 'of' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
This explanation may well be incorrect...
