Just a brief rehash of setting up the kit.
first is this kit requires you to download the source for the version of unreal you want to build on.
the regular down load from unreal does not contain the features for backend use. ie. db, chat, etc. so you have to download the source from github.
this also requires visual studio to compile the engine.
once you have your engine compiled you have to tell the project which version it is going to use. then it should do a quick build of the project and open.
the plugins that are required should already be in the kit and wont need further tweaks.
additionally there is setup for the db, chat, scripts and patcher. its not difficult but does require some basic skills. which ofc you can develop.
the kits docs are a bit vague at some levels but there is enough to get you to a running demo of the game. remember this is a starter kit. its not meant to click a few buttons and have a running game. this is a basic framework and all the needed parts to setup a basic project.
