Hi all
I’m adding an addition to a small barn with a gambrell roof. The main part doesn’t have any roof vents. I would like to add a ridge vent went I’m completing the roof on the addition.
I’m thinking all I’ll have to do is remove the top cap of shingles and cut the sheathing back and add the ridge vent. Is there more to this than meets the eye?

That's pretty much it. Most ridge vents are of the "shingle-over" style, so you cover them with cap shingles after they're installed. But some are left exposed.
Fairly complete instructions should come with the vent product. Avoid the products that are just mesh -- get one of the molded plastic products.
You'll also need soffit vents to supply the ridge vent with air...Buic
Of course, in a true barn structure with no "ceiling" the eave vents are likely unnecessary. If the attic/loft area is fairly well sealed, however, then some sort of venting near the eaves is advised.

This is a small barn, about 20 x 22. The down stairs will be my woodshop, the upstairs my weight room.
The height to the ridge is about 12 feet. The plan is to use 1x3 along the rafters to space out some rigid foam insulation up to the ridge vent. With vents along the full length of the soffit. The same area over my addition will be used to store all the seasonal decorations my wife likes to collect. (read crap).
Why?
