+# ReScript Deno
+
+ReScript bindings to Deno APIs.
+
+## FAQ
+
+### Isn't Deno for TypeScript?
+
+Deno can host plain JavaScript. That means any Alt-JS languages can be hosted either.
+
+### But Why?
+
+Deno is a good platform. Even better with the better language.
+
+### How can I verify this works?
+
+You can run [examples](./examples) with the `yarn example` script.
+
+```bash
+# Build once before running.
+yarn install
+yarn build
+
+yarn example example/catj.bs.js package.json
+```
