1- LogOut from your own Ubisoft account in uplay launcher and login to the uplay account that you recieved .
2- Now launch steam and login with the steam account that you recieved and launch the Rainbow Six Siege .
3- In First Time Launch It ll ask you to link the uplay account to steam . ! Make Sure The Uplay Account That You Are Linking It Its Same With One Yours .
4- After Linking Account Your Game Will Be Launched And you are ready to Play Ranked Rainbow Six Siege Match

Be CareFull With What Uplay Account That You Are Linking It .
-Unfortunely because of steam rules and linking process limits if you link wrong uplay account to your steam(fresh steam that we provided to you in your order)
we cant provide you any replacement for your steam account and you have to buy a new fresh r6s steam account in order to be able to login with the uplay that you want to be able access to your old/new account
