 ### Build Gen AI Application
+
+In following quickstart we will show you how easy it is to build gen ai application with Arch gateway. We will build a currency exchange agent using following simple steps. For this demo we will use `https://api.frankfurter.dev/` to fetch latest price for currencies and assume USD as base currency.
+
+Create `arch_config.yaml` file with following content,
+
+```yaml
