+# Actors
+
+This package contains shims for abstracting over different actor versions.
+
+## Design
+
+Shims in this package follow a few common design principles.
+
+### Structure Agnostic
+
+Shims interfaces defined in this package should (ideally) not change even if the
+structure of the underlying data changes. For example:
+
+* All shims store an internal "store" object. That way, state can be moved into
+  a separate object without needing to add a store to the function signature.
+* All functions must return an error, even if unused for now.
+
+### Minimal
+
+These interfaces should be expanded only as necessary to reduce maintenance burden.
+
+### Queries, not field assessors.
+
+When possible, functions should query the state instead of simply acting as
+field assessors. These queries are more likely to remain stable across
+specs-actor upgrades than specific state fields.
+
+Note: there is a trade-off here. Avoid implementing _complicated_ query logic
+inside these shims, as it will need to be replicated in every shim.
