 # CSharpToJavaScript
-### Description
 Brute forcing conversion(translation) from C# to Javascript.
 
+This is a personal project with purpose to learn and understand better c# and js at the same time. Many stuff is not supported and some won't. Updates will be happening when I'm using this library.(irregular)
+
 | C#     | Javascript |
 | ---      | ---       |
 | <pre>using static CSharpToJavaScript.APIs.JS.GlobalThis;<br>namespace ConsoleApp1twest.CSharp;<br><br>public class Test<br>{<br> public Test()<br> {<br>   Console.Log("HelloWorld!");<br> }<br>}</pre> | <pre>class Test<br>{<br> constructor()<br> {<br>   console.log("HelloWorld!");<br> }<br>}</pre>|
 
+## How to use
+*Nuget package will be available once I figure out how to do docs for api(should be easy) and what to do with esmascript and how to convert to c#.*
+
+- Download a library(Code-Local-Download ZIP)
+- Create c# project or use existed one
+- Follow [this](https://learn.microsoft.com/en-us/dotnet/core/tutorials/library-with-visual-studio?pivots=dotnet-7-0#add-a-project-reference) to add reference to project
+- In the Main method add:
+```csharp
+Assembly assembly = Assembly.GetExecutingAssembly();
+CSTOJS cstojs = new(assembly);
+cstojs.Generate2Async("FULL PATH TO CSHARP FILE YOU WHAT TO CONVERT");
+```
+- Run program and file will be generated in output path(default is "Directory.GetCurrentDirectory()") with name "main.js"(default)
+- See below for simple example "HelloWorld"
+
+## Example "HelloWorld"
+Program.cs
+```csharp
+using System.Reflection;
+using CSharpToJavaScript;
+namespace ProgramTest;
+
+public class Program
+	{
+		public static void Main()
+		{
+			Assembly executingAssembly = Assembly.GetExecutingAssembly();
+			CSTOJSOptions opt = new()
+			{
+				CustomCSNamesToJS = new List<Tuple<string, string>>()
+				{
+					new Tuple<string, string>("Console","console"),
+					new Tuple<string, string>("WriteLine", "log")					
+				},
+				OutPutFileName = "test.js"
+			};
+
+			CSTOJS cstojs = new(executingAssembly, opt);
+			cstojs.Generate2Async("C:\\GitReps\\Program\\Program\\CSharp\\test.cs");
+		}
+
+	}
+```
+test.cs
+```csharp
+namespace ProgramTest;
+
+public class Test
+	{
+		public Test()
+		{
+			Console.WriteLine("HelloWorld");
+		}
+
+	}
+```
+Above code will generate test.js file that contains:
+```javascript
+class Test
+{
+ constructor()
+ {
+   console.log("HelloWorld");
+ }
+}
+```
+## Some Todos
+- [ ] More comments in code, especially in [CSTOJSOptions](https://github.com/TiLied/CSharpToJavaScript/blob/master/CSharpToJavaScript/CSTOJSOptions.cs)
+- [ ] Wiki?
+- [ ] Better and more examples
+- [ ] Figure out how to do docs for [api](https://github.com/TiLied/CSharpToJavaScript/tree/master/CSharpToJavaScript/APIs/JS)
