 We generate a good default [`tsconfig.json`](https://github.com/typed-ember/ember-cli-typescript/blob/master/blueprints/ember-cli-typescript/files/tsconfig.json), which will usually make everything _Just Work™_. In general, you may customize your TypeScript build process as usual using the `tsconfig.json` file.

+However, there are a few things worth noting if you're already familiar with TypeScript and looking to make further or more advanced customizations (but _most_ users can just ignore this section!):
 
 1. The generated tsconfig file does not set `"outDir"` and sets `"noEmit"` to `true`. The default configuration we generate allows you to run editors which use the compiler without creating extraneous `.js` files throughout your codebase, leaving the compilation to ember-cli-typescript to manage.
 
-   You _can_ still customize those properties in `tsconfig.json` if your use case requires it, however. For example, to see the output of the compilation in a separate folder you are welcome to set `"outDir"` to some path and set `"noEmit"` to `false`. Then tools which use the TypeScript compiler \(e.g. the watcher tooling in JetBrains IDEs\) will generate files at that location, while the Ember.js/[Broccoli](http://broccolijs.com/) pipeline will continue to use its own temp folder.

 2. Closely related to the previous point: any changes you do make to `outDir` won't have any effect on how _Ember_ builds your application—we run the entire build pipeline through Babel's TypeScript support instead of through the TypeScript compiler.
 3. Since your application is built by Babel, and only _type-checked_ by TypeScript, we set the `target` key in `tsconfig.json` to the current version of the ECMAScript standard so that type-checking uses the latest and greatest from the JavaScript standard library. The Babel configuration in your app's `config/targets.js` and any included polyfills will determine the final build output.
-4. If you make changes to the paths included in or excluded from the build via your `tsconfig.json` \(using the `"include"`, `"exclude"`, or `"files"` keys\), you will need to restart the server to take the changes into account: ember-cli-typescript does not currently watch the `tsconfig.json` file. For more details, see [the TypeScript reference materials for `tsconfig.json`](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html).
