How arenas work?

Ey, I'm new in Lordaeron and trying to get PVP gear, as I cannot stay with PVP points gotten from BG all time I was wondering to make some arenas, how do they work?

Can I make them with no limit of GS?
If I make some weekly will I get some points to start getting money for PVP arenas/honor points?

Thanks for answering

All you need is to make arena team, invite a player into it and join arena. Play minimum of 10 games to receive arena points. You can even lose all 10 games and still receive points, like many do.
Make sure you don't lose to/feed any specific team, that is called "wintrading" and is against rules.
