 ## Description
 netDxf is a .net library programmed in C# to read and write AutoCAD dxf files. It supports AutoCad2000, AutoCad2004, AutoCad2007, AutoCad2010,  AutoCad2013, and AutoCad2018 dxf database versions, in both text and binary format.
 
-I tried to keep the use as simple as posible, for example you will not need to fill up the table section with layers, styles or line type definitions. The DxfDocument will take care of that everytime a new item is added and the load and save its done with just one line of code.
-If you need more information, you can find the official dxf documentation in

 Code example:
 
 ```c#
 public static void Main()
-   { 
-      // by default it will create an AutoCad2000 dxf version
-      DxfDocument dxf = new DxfDocument();
-      // add your entities here
-      dxf.AddEntity(entity);
-      // save to file
-      dxf.Save(filename);
+{
+	// your dxf file name
+	string file = "sample.dxf";
+
+	// by default it will create an AutoCad2000 DXF version
+	DxfDocument dxf = new DxfDocument();
+	// an entity
+	Line entity = new Line(new Vector2(5, 5), new Vector2(10, 5));
+	// add your entities here
+	dxf.AddEntity(entity);
+	// save to file
+	dxf.Save(file);
 
-      // load file
-      DxfDocument dxfLoad = DxfDocument.Load(filename);
-   } 
+	bool isBinary;
+	// this check is optional but recommended before loading a DXF file
+	DxfVersion dxfVersion = DxfDocument.CheckDxfFileVersion(file, out isBinary);
+	// netDxf is only compatible with AutoCad2000 and higher DXF version
+	if (dxfVersion < DxfVersion.AutoCad2000) return;
+	// load file
+	DxfDocument loaded = DxfDocument.Load(file);
+}
 ```
