SQL 2008 r2 replication with SQL CE 3.5 sp

I am looking for guidance in setting up replication (Merge) between SQL server 2008 r2 (based at HQ) and severeal SQL CE databases on Windows mobile 6.5 handhelds

Is this even possible?if  so where is the best place to start.

I am interested to know if we wil need to set up each device as a subscriber to the SQL server 2008 r2 publisher?
