how to setup Sql Server 2012 Always On 3 Nodes?

Hi,

I want to setup Sql Server 2012 in 3 Nodes with AlwaysOn feature.

* Node 1 and Node 2 is my Primary server and stays in Primary data center and uses shared disk.

* Node 3 stays in DR Data center which uses local disk.

I will use Node1 & Node2 as Production DB as active/active cluster, and Node 3 will use for

DR database ( synchronized commit, Read only for reporting Purpose ) .

Please help me how to configure full setup according to my requirement.

Thanks
