help linking to online account

Hi I need tutorial Rendezvous style registration to storing the device id in website database along with the unique token (in website database and device registry) .
Data in registry is stored even if the device boots and for every reset, all registry data you have stored will be deleted.
I read documentation https://blog.roku.com/developer/2011/07 ... e-account/ and http://sdkdocs.roku.com/display/sdkdoc/ ... nd+Linking
not found it.
anyone help me the petition Thanks.
