-gem 'hyku_knapsack', github: 'samvera-labs/hyku_knapsack', branch: 'upstream_main'
+#
+# When you use a knapsack for Hyku development, which we recommend, you'll want to ensure that your
+# local knapsack repository has a `'required_for_knapsack_instances'` branch (which it should by
+# default).  Due to some tomfoolery, of knapsack, the branch name
+# (e.g. `required_for_knapsack_instances`) must be checked out locally in the knapsack environment
+# that you use to build Docker.
+#
+# Why not use `main`?  We need a stable SHA for building HykuKnapsack prime
+# (e.g. samvera-labs/hyku_knapsack).  Why the stable SHA?  Because when we bundle a knapsack, the
+# Hyku submodule uses the SHA of the locally checked out branch specified in the gem spec.  Which
+# can create a chicken and egg issue; namely I need to update Hyku with a new SHA for Knapsack, but
+# to update Knapsack's submodule reference to Hyku, I need a new SHA for knapsack.  Thus, I can never
+# use a "regular branch".  Instead we need to use a separate more stable for Knapsack.
+#
+# Thus the hopefully descriptive `required_for_knapsack_instances`.
+#
+# tl;dr - Have a local `required_for_knapsack_instances` branch on your knapsack repository
