The best thing to do is simply to follow the instructions provided by the webdrive client you plan to use. For example, several of us have had good luck with WebDrive: http://www.webdrive.com/

I'd planned to simply post a few screenshot of the install/setup process in the docs, but not address javascript usage. Only simple docs were planned because setup is so specific to the client you use. Let me know if it would be helpful for me to dig up further specific info for you.
