SignalR - HubContext and Hub.Context

I am new to signalR and read the API and play with it. a little confused in the hub and its context.

That is Hub.Contextnot HubContext.

HubContext I can get from GlobalHost.ConnectionManager.GetHubContext<THub>()

and Hub.Contextgives me HubCallerContextwhich I am not sure how to use.

What is their relationship? How can i get HubContext from Hubor Hub from HubContext?

{        
    public void Foo()
    {               
        // These two are equivalent
        Clients.Caller.bar();
        Clients.Client(Context.ConnectionId).bar(); // Context.ConnectionId is the client that made the request connection id
    }
}
