 ## Behavior
 
-- Property reads and writes go through a proxy.
-- Nested property access is reactive.
-- Mutations update the store in place.
+- `createMutable` creates mutable shared state through a reactive proxy. Property reads and writes go through that proxy, and nested property access is reactive.
+- Writes, deletes, and array mutator methods are batched through the proxy while updating the store in place.
+- This is primarily a client-side reactive proxy mechanism.
 - Getters and setters defined on the initial object remain available on the mutable store.
