Incorperating Github Fritzing Parts into Fritzing

I read somewhere that all the Fritzing parts including any new parts are all now stored in Github.
As I required a part which was not in the Fritzing parts I decided to join Github to have access to all the parts and downloaded the entire Fritzing parts library stored there. (All are .fzp)
As I do not know how to incorporate them into the standard Fritzing program's parts I have not used any.
From your email it seems that it is not necessary as Fritzing updates the library automatically.
