Fire TV noob setup

Hi Everyone. Please forgive if i have missed something. Complete noob here, getting started.
I am trying to add 2 Amazon firesticks that i have to my HA config. I am running HA on a windows PC but unsure where to start with the instructions at https://home-assistant.io/components/media_player.firetv/ . Has anyone got a steb by step i could use?
any help appreciated
