How to use added typings in typescript

I am trying to learn Typescript, and have set up a basic typescript structure following this tutorial. I need to add typings to the project now. So I looked around and found typings. Then I added `JQuery`,`Lodash`, and `D3` using typings. My project structure looks like this: ``` ├── dist │   ├── chart.js │   ├── greet.js │   └── main.js ├── gulpfile.js ├── package.json ├── src │   └── ts │   ├── chart.ts │   ├── greet.ts │   └── main.ts ├── tsconfig.json ├── typings │   ├── globals │   │   └── jquery │   │   ├── index.d.ts │   │   └── typings.json │   ├── index.d.ts │   └── modules │   ├── d3 │   │   ├── index.d.ts │   │   └── typings.json │   └── lodash │   ├── index.d.ts │   └── typings.json └── typings.json ``` This is my `tsconfig.json` file: ``` { "files": [ "src/ts/*.ts" ], "compilerOptions": { "noImplicitAny": true, "target": "es5" } } ``` My question is, how do I add the `*.d.ts` files which I have in `typings` directory in my `main.ts` file and start using jQuery's `$` or D3's `d3`? I noticed `index.d.ts` file in `typings` which looks like this: ``` /// <reference path="globals/jquery/index.d.ts" /> /// <reference path="modules/d3/index.d.ts" /> /// <reference path="modules/lodash/index.d.ts" /> ``` So my guess is, I just need to add this file somewhere in my `main.ts` file or in my `tsconfig.json` file(instead of manually adding each `.d.ts` file). Am I right? Thanks.
