1) Make two if you want you can make one shortcut and name them server and/or client
2) Open the console,terminal or comand prompt and type the path to your folder (for faster and easier results put it in desktop) in this case cd Desktop\teewars
and then type dir to see the directory (note that cd is to change directory without it, it will not work)
3) To make the server type: (or the way you called what is going to be the server) server.lnk -s -n test server
(the .lnk ending is for link since it is a shortcut (or the ending of your file) )                           ^
                                                                                                             |
                                                                                                             |
                                                                                                       (or the name you want your server to be)
4) To enter the server type in another console,terminal or command prompt and type: (or the way you called what is going to be the client)
client.lnk  -c 127.0.0.1. to join the server.
5) Enjoy!
