UE4 and Modding - where to start?

Hey guys, i know this is all over the place, but, i wasn’t able to find anything current. it was all 4.9 (2014-2015) posts.

With current build (4.16) what would i need to do to get my project to be able to accept player created mods?
Much like Ark. Having a steam setup/workshop and allowing players to make maps and other mods … ?

I did find a WIKI on this, but, again, it was some really dated information. I did find some posts about it all, but, it was all old information and i wasn’t sure if any of it was updated.

Is this something i will need to speak with Epic about to get some sort of editor slot for players to use (much like paragon, UT, and Ark (“modding”)) ?

Thanks in advance!

I also am interested in this.
