 We've tried to replicate the behavior of the Unity3D LLAPI to make using ZeroTier as easy as possible. All you need to do is add the `ZeroTierSDK_Unity3D_YOUR-PLATFORM` library to the `assets/plugins` folder of your project and start using the `ZeroTierNetworkInterface`:
 
+
+To start things off, go check out [ZeroTierSockets_Demo.cs](). Here are some examples of how to use the `ZeroTierNetworkInterface`:
+
+## Server example
+```
+Thread connectThread = new Thread(() => { 
+			// Socket()
+			connection_socket = zt.Socket ((int)AddressFamily.InterNetwork, (int)SocketType.Stream, (int)ProtocolType.Unspecified);
+			Debug.Log ("sockfd = " + connection_socket);
+
+			// Bind()
+			int port_num;
+			int.TryParse(port.text,out port_num);
+			int bind_res = zt.Bind(connection_socket, "0.0.0.0", port_num);
+			Debug.Log ("bind_res = " + bind_res);
+
+			// Listen()
+			int listen_res = zt.Listen(connection_socket, 1);
+			Debug.Log ("listen_res = " + listen_res);
+
+			// Accept() loop
+			Debug.Log("entering accept() loop");
+			int accept_res = -1;
+			while(accept_res < 0)
+			{
+				//yield return new WaitForSeconds(1);
+				accept_res = zt.Accept(connection_socket);
+				Debug.Log ("accept_res = " + accept_res);
+
+			}
+
+			char[] msg = new char[1024];
+			int bytes_read = 0;
+			while(bytes_read >= 0)
+			{
+				//Debug.Log("reading from socket");
+				bytes_read = zt.Read(accept_res, ref msg, 80);
+
+				string msgstr = new string(msg);
+				Debug.Log("MSG (" + bytes_read + "):" + msgstr);
+			}
+		});
