Shady Hugelkultur

Hello! I am rearranging some things in my yard, and as a result I have a ton of extra soil…. My plan was to build a hugelkultur bed with it in the back, but it’s a pretty much full shade under the south facing dripline of some very mature black walnuts. My plan is to focus on a native woodland garden back there, since conditions aren’t great for edibles. I am in Wisconsin, zone5b. Anyone have some advice on building one in the shade? Or photos of yours for inspiration? My goals are feeding the family and the wildlife- preferences for natives if not specifically a crop for us.
