You were given a free TV. Now go the store (Walmart, Target, Best Buy) and either purchase a $20 Roku Voice Remote (will work with both RokuTVs and Roku devices) or an inexpensive universal streaming remote ($10-20 IR based) that is compatible with RokuTVs in order to complete the setup.
Yes, the above will require some effort on your part.
