   You can configure `package.json` with more entry points besides [main](https://docs.npmjs.com/files/package.json#main).
 
-  The **Quickstart Library** seed uses a similar set of entry points as Angular itself, 
-  aimed at maximizing compatibility:
+  The recommended set of entry points is as follows:
 
   - `main` (default): an ES5 [UMD](https://github.com/umdjs/umd) bundle that can be consumed anywhere.
   - `module`: a flat ECMAScript module (FESM) bundle containing ES5 code.
   - `es2015`: a FESM containing ES2015 bundle.
   - `typings`: TypeScript and the AOT compiler will look at this entry for metadata.

-  "es2015": "./dist/angular-quickstart-lib.js",
-  "typings": "./dist/angular-quickstart-lib.d.ts",
