+## Railway Deployments
+
+This repo hosts two Railway services, each with its own config file:
+
+- Example app: Root Directory `/example`, Railway Config File `/example/railway.toml`
+- Docs site: Root Directory `/docs`, Railway Config File `/docs/railway.toml`
+
+Note: Railway does not automatically follow the Root Directory when selecting a
+config file, so you must set the absolute config path per service. A root
+`railway.toml` is intentionally not used.
