Addon is called Gnomesequencer and you can download it from Twitch where you download all your other addons i presume. Open the addon ingame by typing /gs, copy and paste everything inside the codebox on the macro from the link you have, press import button on the opened addon ingame, paste everything and press import. Drag the ? icon to your actionbar and press, press, press
