echo --- How It Works ---
echo --------------------
echo.
echo If you're a sucker for details, this is what you want to know:
echo This loader will write some lines at the end of config.cfg file, which is located in the portal2\cfg\ directory.
echo These lines are:
echo    bind f2 "toggleconsole"
echo    bind 1 "changelevel map mp_coop_start"
echo    bind 2 "changelevel mp_coop_fling_3"
echo    bind 3 "changelevel mp_coop_wall_intro"
echo    bind 4 "changelevel mp_coop_tbeam_redirect"
echo    bind 5 "changelevel mp_coop_paint_come_along"
echo.
echo If you've already used this loader, you probably have these lines already written in there,
echo but no worries. They'll be written at the end of the file, but it's all the same so...
echo.
echo The first keybind is used to access the developer console with the F2 key.
echo Now, if you have an US layout keyboard you don't really need this keybind, but since not everyone has one...
echo About the changelevel binds. These allow you, as the host, to change to those levels in the game.
echo I didn't pick up random levels. These are the first levels of every chapter. These are useful because the game won't change chapters by itself.
echo At the end of every chapter you'll wind up in a level known as The Hub. When this happens, just tap the key
echo that corresponds to the chapter you want to play next. Just keep track of the chapter you're playing and do your math :P
echo.

echo.
echo This is how you play Portal 2 Co-Op on LAN (or VPN like tunngle):
echo (Note that it must be done in this order.
echo The client will search for the server BEFORE it is even created)
echo Also put this loader in the Portal 2 folder, where the portal2.exe file
echo is located or it won't work.
echo.
echo (Client)
echo 1- The host tells the client their IP
echo 2- Using this loader, go to the Client menu and types in the host's IP.
echo    The game will launch and start looking for a server on that IP.
echo.
echo (Host)
echo 3- While the client is looking for a server on your IP, using this loader,
echo    go to the Server menu and select the chapter you want start at.
echo    When your game starts, the client will find a server on your IP and the fun begins :D
echo.

echo.
echo Now, because the game doesn't change chapters automatically at the end of the chapters,
echo (at the end of every chapter you have to insert a disc
echo in a projector and GlaDOS will dispose of you)
echo the HOST must change chapters manually. To do that, he can type in changelevel mapname
echo OR use the keys from 1 to 5 to change to the respective chapter
echo (spoiler: there are 5 chapters :P)
echo This is only possible because of this loader.
echo.
echo Note that everyone should have some ports open (if they use a router or DLS modem).
echo For tunngle, the default port is 11155 UDP.
echo If you're having trouble, open the game's default port. It's 27015 UDP.
echo If you don't know how to do this, check out versatile's tutorial:
echo    http://www.youtube.com/watch?v=S8BBdJ05DVw

echo or search for "port forward" online.
