+====================================
+
+1) The settings file
+ The file is stored in a simple human readable-editable JSON format. If it doesn't exist, the engine will recreate it with default settings. Else, it'll load it up and use the settings described
+
+ WHAT EACH SETTING DOES (THERE ISN'T A LOT):
+ VSync: Sets the vsync mode.
+ 0 - off
+ 1 - on
+ 2 - adaptive
+
+ WindowMode: How the window will appear
+ 0 - Normal (windowed)
+ 1 - Minimized
+ 2 - Maximized
+ 3 - Fullscreen
+
+ NoBorder: Remove the border of the window (Useful for appearing like fullscreen but acting like a window)
+ Width/Height: The resolution of the screen. This is rather self explanatory
+ ShadowMapSize: The size (width and height) of the shadowmap. Higher values will result in a better looking map but is more perfomance intensive.
+ Samples: MSAA samples for antialiasing
+ AnisotropicFiltering: How much anisotropic filtering should be applied to textures. This makes textures that aren't perpendicular to the camera look better.
+ GlobalVolume: Global volume override for all audio.
+ ShowFPS: Draw an FPS indicator ingame
+ ShowConsole: Show the debug console. Do this if bad things are happening.
+
+2) I'm not responsible if it breaks your everything
+ I was nowhere near isle 7
