+C#
+===
+
+Introduction
+--------------
+
+C# is a high-level programming language developed by Microsoft. In Godot it is implemented with the Mono 5.2 .NET framework including full support for C# 7.0.   
+
+.. note:: This is **not** a full-scale tutorial on the C# language as a whole.
+        If you aren't already familiar with its syntax or features,
+        see the `Microsoft C# guide <https://docs.microsoft.com/en-us/dotnet/csharp/index>`_.
+
+Necessary Downloads
+-------------------------
+
+To use C# in Godot you must have `Mono <http://www.mono-project.com/download/>`_
+installed (at least version 5.2), and use a Godot version with Mono enabled, which adds C# support next to the existing options of GDScript, visual scripting and C++.
+
+Windows users also need MS Build 15.0, which comes bundled with Visual Studio 2017,
+or can be downloaded separately with `build tools for Visual Studio 2017 <https://www.visualstudio.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=15#>`_.
+
+
+History
+--------
+
+Back in 2016 the Godot team reached out to Microsoft, with Miguel de Icaza's 
+support, to see if they would consider funding C# support being added to 
+Godot. Microsoft agreed and gave the team a $24,000 donation to work on adding
+C# support. Thanks to that donation, Juan Lineietsky and Ignacio Roldán 
+Etcheverry were able to work on bringing C# support to Godot using the Mono 
+.NET framework. Support was added to Godot version 3.0 using mono 5.2, giving users 
+the power of C# in their game making.
+
+Example
+-------
+
+Here's a blank C# script with some comments to demonstate how it works. 
+
+.. code-block:: csharp
+
+    using Godot;
+    using System;
+
+    public class Path : Path
+    {
+        // Member variables here, example:
+        private int a = 2;
+        private string b = "textvar";
+
+        public override void _Ready()
+        {
+            // Called every time the node is added to the scene.
+            // Initialization here
+        }
+
+        public override void _Process(float delta)
+        {
+            // Called every frame. Delta is time since last frame.
+            // Update game logic here.
+        }
+    }
+
+
+Configuring an external editor
+-----------------------------------
+
+While Godot does have its own scripting editor, its support for C# is kept
+minimal, and it's reccomended that you use an external IDE or editor, such as
+Microsoft Visual Studio Code, or MonoDevelop, which provide auto-completion,
+debugging and other features useful when working with C#.
+To set it up, in Godot click on ``Editor``, then ``Editor Settings``. Scroll 
+down to the bottom, to the ``Mono`` settings. Under Mono click on ``Editor``,
+and on that page choose your external editor of choice.
