Meeting my boyfriend's family for the first time this upcoming Friday. Any advice appreciated?

My Boyfriend has asked that I meet his family this Friday before his hockey game.
We met in June via hinge and made things official towards the end of August.

Things have been going well so far, so I have attended 2 of his hockey games before, and he suggested I attend this upcoming Friday's game as he will be playing against his brother, and his parents will be there, alongside his brother.

So I agreed, and of course, this is nerve-wracking, as earlier this month, he took me to a work gala and introduced me to his colleagues.

So any advice on meeting parents and siblings for the first time?

I'm 25 he is 26.
