Setup is already pretty painless if you read the docs, but for people that don't read, it's not super intuitive where to go to build the solution and generate the engine. For people that are less comfortable with game dev, it might also not be obvious that the compiled engine is output into the bin directory even though that is typical.
Easy solution would be to add a 1-click setup script to the root directory, next to the README that handles all that for you. Shouldn't be too difficult to have the script build the solution and create a shortcut to the newly created engine executable in the root directory so people can run the script and are off to the races.
