-## IntelliSense support and type checking for VS Code
-
-The `ol` package contains a `src/` folder with JSDoc annotated sources. TypeScript can get type definitions from these sources with a `jsconfig.json` config file in the project root:
-```js
-{
-  "compilerOptions": {
-    "checkJs": true,
-    // Point to the JSDoc typed sources when using modules from the ol package
-    "baseUrl": "./",
-    "paths": {
-      "ol": ["node_modules/ol/src"],
-      "ol/*": ["node_modules/ol/src/*"]
-    }
-  },
-  "include": [
-    "**/*.js",
-    "node_modules/ol/**/*.js"
-  ]
-}
-```
-Project template with this configuration: https://gist.github.com/9a7253cb4712e8bf38d75d8ac898e36c.
-
-Note that the above only works when authoring in plain JavaScript. For similar configurations with a `tsconfig.json` in TypeScript projects, your mileage may vary.

 ## Supported Browsers
 
 OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io) for `requestAnimationFrame` and `Element.prototype.classList` are required, and using the KML format requires a polyfill for `URL`.
