+### Sourcemaps
+
+To enable TypeScript sourcemaps, you'll need to add the corresponding configuration for Babel to your `ember-cli-build.js` file:
+
+```ts
+const app = new EmberApp(defaults, {
+  babel: {
+    sourceMaps: 'inline',
+  },
+});
+```
+
+(Note that this _will_ noticeably slow down your app rebuilds.)
