In order for your gameplay to be streamed inside the Rival App, you must have a Twitch streaming account.  Simply connect your Twitch account with your Rival account inside your account's Rival Passport.  

If you change your Twitch account name in the future, you can update it within Passport.

For help on signing up for Twitch or if you have an existing Twitch account, learning how to start your broadcast stream on your game console, please go to the help sections for Xbox or PlayStation so watch the Twitch related videos.
