how to install the Hilo DDR

Dear Intel FPGA support/expert,

I just got a brand-new Arria10 Dev Kits. by default, the DDR is not installed on the J14. and the heat think on the FPGA is on top of the socket, I guess need to be removed first to install the Hilo DDR on J14, I didn't find any detailed instruction in the "Arria 10 FPGA Development Kit User
Guide", and "Q U I C K S TA R T G U I D E", is there a step-by-step instruction to connect the board to the computer and power supply, include install the ddr HiLo module? please send me a link to the file, or the section in the user guide if I missed the chapters.

Thank you,

David
