Truss bracing questions

[nxs450]

Finally got concrete work done and framed up the garage over the weekend. This coming weekend I plan on installing roof trusses.
I'm not sure where the bracing goes on them, and can't make out anything on the drawings sent. Garage is 20 x 28 so trusses are 20ft wide with 4/12 pitch.
Anyone know how to read these damn things or what is required by code.

There is a bracing note directly below the center of the truss, that states...."Attach a rigid ceiling to the bottom chord, OR apply bracing at 2'2" on center."....seems like a lot of bracing to me, normally would be further apart than that.....could be that company's default setting. When I run that truss with no ceiling attached, 1 row of bracing down center of truss is sufficient.
