 ## How to use TypeScript without `ember-cli-typescript`?
 
-In the [ember-cli-babel](https://github.com/emberjs/ember-cli-babel#enabling-typescript-transpilation) docs, it mention that in your `ember-cli-build.js`, you can specify:

+Apps and v1 addons need to configure Babel to compile TypeScript files via the `ember-cli-babel` config, as described in the [ember-cli-babel](https://github.com/emberjs/ember-cli-babel#enabling-typescript-transpilation).
+
+Additionally, you will need the `tsconfig.json` generated by the Ember TypeScript blueprint (see above), and then can run [`glint`](https://typed-ember.gitbook.io/glint) or `tsc` directly on the CLI. (Again, see the official docs for details!)

+### Apps
+
 ```js
 'ember-cli-babel': {
   enableTypeScriptTransform: true,
 },
-```
-
-For v1 addons, this would be specified in the node-land `index.js`:
-```js
-module.exports = {
-  name: require('package').name,
-  options: {
-    'ember-cli-babel': {
-      enableTypeScriptTransform: true
-    }
-  }
-}
