 The box-js repository from git includes a `boilerplate.js` file. This file defines some stubbed versions of common browser objects such as document. Try rerunning your analysis with the `--prepended-code=DIR/boilerplate.js` option, where `DIR` is the directory of the cloned box-js repository. The `--prepended-code` option tells box-js to prepend the JavaScript in the given file to the sample being analyzed.
 
+Note that you can copy boilerplate.js and add your own stubbed classes, objects, etc. as needed.

 ## Batch usage
 
 While box.js is typically used on single files, it can also run batch analyses. You can simply pass a list of files or folders to analyse:
