How do you open inbox on Facebook?

[Augustus]

I'm new to Facebook and someone just sent me very important Inbox, but I don't want to seem like an idiot by asking them what an "inbox" is. Where do I find it to look at messages?

https://www.facebook.com/messages/

or from top bar click on chat icon - between icon for person and icon for globe (notifications)

In the start page go to message and see your inbox.
