Installing a SSD for additional storage

Guys,

I have a new M15  on the way and arriving tomorrow. :BigSmile:

Configuration is:

Intel i7-8750H, 15.6" 300 Nits FHD 144hz Refresh Rate -16GB, 2x8GB, 512GB PCIe M.2 SSD, RTX 2060 6GB (small battery)

I want to add a 2.5 inch SSD as drive D:. I searched for past info here and know it's probably there but can't locate again.

My question is, what am I going to find once I open the cover? WIll mounting brackets and wires be there? also what configuration if any, will I need to perform? And finally, are there any guides/resources out available other than the Dell service manual?

All helpful comments appreciated.
