+Hosts can enable the `derive` feature on `decodal` to keep a Rust struct, the Decodal schema, and the decoded result in sync.
 The derive implements two traits from the `decodal` crate:
 
 - `DecodalSchema`: builds a `HostValue` schema that can be passed to `Engine::bind_global`.
 - `DecodalDecode`: decodes materialized `Data` back into the Rust type.
 
 ```rust
-use decodal::{DecodalDecode, DecodalSchema, EmptyLoader, Engine};
-use decodal_derive::Decodal;
+use decodal::{Decodal, DecodalDecode, DecodalSchema, EmptyLoader, Engine};
