+# this directory is for explicit .env for settings `NODE_ENV` for ncc build
+
+Since the ncc does not opt us to set runtime env, so we'll need to load & set the env manually.
+
+```ts
+import dotenv from "dotenv";
+dotenv.load({
+  path: "./.runtime-env/.env",
+});
+```
+
+## Note for contributors
+
+Is this required?:
+
+Not essential, but some of our modules use logging conditioning based on `NODE_ENV !== "production"` not `NODE_ENV === "development"`.
+
+So in most case, this will not change the core engine's logic behind, this is for disable verbose logging at this point.
