+## Automatically deserializing JSON request bodies in Rust HTTP
+
+This sample shows using the `http::Request<Json<T>>` request type to accept JSON and automatically deserialize it into a Rust struct that implements `serde::Deserialize`.
+
+To test it, run `spin up --build` and then POST to localhost:3000 e.g.:
+
+```
+curl -X POST -d '{"name": "Vyvyan"}' localhost:3000
+```
