Flooring Tile - Hardiebacker underlayment question

I want to use a thin layer of this stuff over a plywood floor. What is the proper way to apply it to the floor?
It looks like it would break easily. Do you have to pre- dril it before nailing it down? What kind of nails should be used? How much spacing between panels? I guess I need a 1 thru 10 breakdown on how to proceed. Thanks

Plywood needs to be minimum 5/8" exterior grade.

Min. 3/32" thick dry-set mortar or modified thinset to plywood.

Leave 1/8" gap between sheet edges and stagger sheets so they overlap plywood joints, and do not have 4 corners meeting at one point.

There are printed dots for fastening guide. 1&1/4" galvanized roofing nails, or corrosion resistant screws (deck screws) every 8" over entire surface, stay about 3/4" from edges and 3" from corners. Make sure nails or screws are flush with surface.

Don't forget to use 2" fiberglass joint tape and mud, on all joints during tile installation.

Rick:
Thanks for your reply. Could I use liquid nails or construction adheasive under the hardibacker?

It is not recommended by the manufacturer, and I have not tried it. Perhaps John Nelson, or another of the tile experts will pop in and answer this.
