+You can install ember-cli by following the instructions on [the emberjs website](https://cli.emberjs.com/), or you can keep everything in docker using the [ember-docker scripts](https://github.com/madnificent/docker-ember).  Our examples assume you’ll use ember-docker, which provides the `edi` and `eds` commands. If you're using a globally installed ember-cli, simply remove `edi` from any commands and replace `eds` with `ember serve`.

 ```sh
 edi ember new books
+# Or if using a globally installed ember-cli (see above)
+# ember new books
 ```
