Follow the instructions that came with the Roku. You will need to create an online account including entering secured credit card information. The credit card information is between you and Roku, and Roku does not share this information with KCM. Roku does not charge any fees for their basic service or free channels. There is only a charge to your credit card if you purchase premium channels or other products through the Roku box. Once you are connected, you can add the KCM Roku channel by navigating to the Roku Channel Store with your included Roku remote.
