-## Integrating the AMD version of the Monaco Editor in a cross-domain setup
-
-Here is the most basic HTML page that embeds the editor, using AMD, in the case that the editor sources are hosted on a different domain (e.g. CDN) than the document origin.
-
-More self-contained samples are available at [monaco-editor-samples](https://github.com/Microsoft/monaco-editor-samples).
-
-If you are hosting your `.js` on a different domain (e.g. on a CDN) than the HTML, you should know that the Monaco Editor creates web workers for smart language features. Cross-domain web workers are not allowed, but here is how you can proxy their loading and get them to work:
-
-Assuming the HTML lives on `www.mydomain.com` and the editor is hosted on `www.mycdn.com`.

-# Option 1: Use a data: worker URI

-<script type="text/javascript" src="http://www.mycdn.com/monaco-editor/min/vs/loader.js"></script>
-<script>
-	require.config({
-		paths: { vs: 'http://www.mycdn.com/monaco-editor/min/vs' }
-	});
-
-	// Before loading vs/editor/editor.main, define a global MonacoEnvironment that overwrites
-	// the default worker url location (used when creating WebWorkers). The problem here is that
-	// HTML5 does not allow cross-domain web workers, so we need to proxy the instantiation of
-	// a web worker through a same-domain script
-	window.MonacoEnvironment = {
-		getWorkerUrl: function (workerId, label) {
