-# 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.
