It is easy to use and install. Do the following:
- Install Google Chrome: http://www.google.com/chrome/index.html
- Install the Chrome App Crackle: https://chrome.google.com/webstore/detail/ibfamoapbmmmlknoopmmfofgladlinic
- If you connect anywhere outside of USA, movie & TV show selection is not great. So consider getting an highspeed USA proxy. Foxyproxy is the best one for the job I think: http://getfoxyproxy.org/
- After getting it, set it up withing the Google Chrome. Do: Google Chrome setup -> under the hood
- Enjoy!
