 Source maps can be generated using libraries such as [source-map-index-generator](https://github.com/twolfson/source-map-index-generator). Once you have a valid source map, insert the following line at the top of your compiled code:
 
-    require('source-map-support').install();
+```js
+require('source-map-support').install();
+```
 
 And place a source mapping comment somewhere in the file (usually done automatically or with an option by your transpiler):
 
-    //# sourceMappingURL=path/to/source.map
+```
+//# sourceMappingURL=path/to/source.map
+```
 
 If multiple sourceMappingURL comments exist in one file, the last sourceMappingURL comment will be
 respected (e.g. if a file mentions the comment in code, or went through multiple transpilers).

 This library also works if you use another build process or just include the source files directly. In this case, include the file `browser-source-map-support.js` in your page and call `sourceMapSupport.install()`. It contains the whole library already bundled for the browser using browserify.
 
-    <script src="browser-source-map-support.js"></script>

-    <script>sourceMapSupport.install();</script>
+<script src="browser-source-map-support.js"></script>

 This library also works if you use AMD (Asynchronous Module Definition), which is used in tools like [RequireJS](http://requirejs.org/). Just list `browser-source-map-support` as a dependency:
 
-    <script>
+```html
-      define(['browser-source-map-support'], function(sourceMapSupport) {
+<script>
-        sourceMapSupport.install();
+  define(['browser-source-map-support'], function(sourceMapSupport) {
-      });
+    sourceMapSupport.install();
-    </script>
+  });
+</script>
+```
 
 ## Options
 
 This module installs two things: a change to the `stack` property on `Error` objects and a handler for uncaught exceptions that mimics node's default exception handler (the handler can be seen in the demos below). You may want to disable the handler if you have your own uncaught exception handler. This can be done by passing an argument to the installer:
 
-    require('source-map-support').install({
+```js
-      handleUncaughtExceptions: false
+require('source-map-support').install({
-    });
+  handleUncaughtExceptions: false
+});
+```
 
 This module loads source maps from the filesystem by default. You can provide alternate loading behavior through a callback as shown below. For example, [Meteor](https://github.com/meteor) keeps all source maps cached in memory to avoid disk access.
 
-    require('source-map-support').install({
+```js
-      retrieveSourceMap: function(source) {
+require('source-map-support').install({
-        if (source === 'compiled.js') {
+  retrieveSourceMap: function(source) {
-          return {
+    if (source === 'compiled.js') {
-            url: 'original.js',
+      return {
-            map: fs.readFileSync('compiled.js.map', 'utf8')
+        url: 'original.js',
-          };
+        map: fs.readFileSync('compiled.js.map', 'utf8')
-        }
+      };
-        return null;
