+Setting up raylib in Visual Studio is very simple.
+
+1) Download and install Visual Studio (note, if you have used unity in the past, you probably have this already)
+2) Create a new C# Console Application Project from the File -> New -> Project Menu
+3) After the project is created, Right click on the project and choose "managed nuget projects"
+4) Choose the Browse tab and type in "Raylib".
+5) Select the "raylib-cs" package from the list and choose 'install' from the panel on the right.
+6) Build your raylib game in C# by using the Raylib_cs library.
+
+A simple main program looks like this
+
+`using System;`
+
+`using Raylib_cs;`
+
+`namespace ConsoleApp`
+`{`
+    `class Program`
+    `{`
+        `static void Main(string[] args)`
+        `{`
+            `Raylib.InitWindow(800, 600, "TEST");`
+
+            `while (!Raylib.WindowShouldClose())`
+            `{`
+                `Raylib.BeginDrawing();`
+                `Raylib.ClearBackground(Color.RAYWHITE);`
+
+                `Raylib.DrawText("Hello C# Window", 10, 10, 20, Color.RED);`
+
+                `Raylib.EndDrawing();`
+            `}`
+            `Raylib.CloseWindow();`
+        `}`
+    `}`
+`}`
