Leaderboard online at 4.26 nowdays

I would like to create an online leaderboard with a total score and compare with your personal score saved in a SaveGame file. Also would like to write the leaderboard online and update stats once the match is finished.
Have checked VaREST and Epicleaderboard but I still have no idea how to do it. Which options do we have? If the best way is VaREST, is out there an easy to follow howto?
Thanks.
