oh they did add it to the ue launcher?
didn’t open it much since ark launch ^^
but if it did dl 50go it seem that it’s complete, i don’t see why when passing by the UE launcher we would need the github file but who know ^^
oh seeing this it seem that the update v200 is live now 
and the dev kit did update on steam :o
they just change the bat file to redirect you on the tuto page for the dev kit where there is that :
A: You can get the ARK Dev Kit directly from the Epic Games Launcher. Simply Sign-Up, Download Unreal Engine, and go to the ARK tab!
it seem the dev kit on steam will no more be update ^^
