+# kosher-rust Diplomat interop
+
+Multi-language FFI bridge for [`kosher-rust`](../README.md), built with [Diplomat](https://rust-diplomat.github.io/diplomat/).
+
+## Regeneration
+
+Preset IDs and dispatch tables are generated from the same DSL as [`src/zmanim/presets.rs`](../src/zmanim/presets.rs):
+
+```bash
+cd tools
+uv run python generate-interop.py
+```
+
+This runs automatically from [`build.rs`](build.rs) on every `cargo build -p interop`.
+
+## TypeScript / JavaScript package
+
+Bindings live in [`packages/typescript`](packages/typescript/). Regenerate and test:
+
+```bash
+cd interop/packages/typescript
+npm install
+npm run generate          # diplomat-tool js → lib/
+npm run build:wasm        # cargo build -p interop --target wasm32-unknown-unknown
+npm test
+```
+
+WASM path is configured in [`packages/typescript/diplomat.config.mjs`](packages/typescript/diplomat.config.mjs) (relative to the repo `target/` directory).
+
+## Dart package
+
+See [`packages/dart`](packages/dart/) — run `dart pub get && dart test` after building the native library via the package hook.
