+## Smithy Integration
+
+You can now use `jsonrpclib` directly with [Smithy](https://smithy.io/) and [smithy4s](https://disneystreaming.github.io/smithy4s/), enabling type-safe, 
+schema-first JSON-RPC APIs with minimal boilerplate.
+
+This integration is supported by the following modules:
+
+```scala
+// Defines the Smithy protocol for JSON-RPC
+libraryDependencies += "tech.neander" % "jsonrpclib-smithy" % <version>
+
+// Provides smithy4s client/server bindings for JSON-RPC
+libraryDependencies += "tech.neander" %%% "jsonrpclib-smithy4s" % <version>
+```
+
+With these modules, you can:
+
+- Annotate your Smithy operations with `@jsonRpcRequest` or `@jsonRpcNotification`
+- Generate client and server interfaces using smithy4s
+- Use ClientStub to invoke remote services over JSON-RPC
+- Use ServerEndpoints to expose service implementations via FS2Channel
+
+This allows you to define your API once in Smithy and interact with it as a fully typed JSON-RPC service—without writing manual encoders, decoders, or dispatch logic.
