Version
What version are you using?

tried github master and 1.18

Build
What runtime version are you using?

cannot build --> no runtime used, but 4.8 is installed

Describe the issue
I try to build the project with Visual Studio 2019 Community Edition and it fails in [MPF/DICUI].Library\Aaru\Parameters.cs.
It complains with CS0246 in different lines, first one is in line 14, the next in line 2201.
In general it cannot find "Schemas" and a lot of data types like TrackTypeTrackType, TragFlagsType and so one.

Probably because of [MPF/DICUI].Library is failing to build, everything else could not be build, too (dependencies). Thus all 5 projects failed.

To Reproduce
Steps to reproduce the behavior:

download and extract fresh/clean copy of source
open solution file with Visual Studio 2019 Community Edition
wait until everything is downloaded and setup
try to compile

Expected behaviour
no errors on build

Additional context
I tried to find a solution online, but "Schemas" is not a very good word to search for. And with other words like "TrackTypeTrackType" I had zero hits. There is probably missing some source code, but in wiki (https://github.com/SabreTools/MPF/wiki/Build-a-Local-Copy) there is nothing additional -- as far as I can see. In shorts it's written the "to Reproduce" steps.
What am I missing?

I should probably add a mention there, but you need to run git submodule init to pull down the required project. This isn't a bug, but I do consider it an oversight in my documentation, so I'll leave this open until I fix it.

I've updated the documentation accordingly. Sorry for missing that step in the instructions.
