Although the International Olympic Committee has barred the Russian team from competing in Pyeongchang because of widespread doping at the 2014 Sochi Games, the country will be represented by "Olympic Athletes from Russia" and competing under the Olympic flag.
To be invited, Russian athletes must meet the usual Olympic qualifying standards but also "be considered clean to the satisfaction of the panel," meaning they can't have been previously banned for doping and must face extensive pre-games drug testing.
It's not yet clear if Russian athletes plan to challenge those requirements in court.
