can you help me?

First i created a folder called MyStartupItem on directory /Library/StartupItems/

After this i created my shell script like in a tutorial that i found on the web.
_______________________________________________________________
#!/bin/sh
. /etc/rc.common

# start subroutine
StartService() {
# Insert your start command below. For example:
ConsoleMessage "opening chess"
open /Applications/Chess.app
# End example.
}

StopService() {
# Insert your stop command(s) below. For example:
#killall -TERM mydaemon
#sleep 10
# killall -9 mydaemon
# End example.
}

# The restart subroutine
RestartService() {
# Insert your start command below. For example:
#killall -HUP mydaemon
# End example.
}

RunService "$1"

I created too a StartupParameters.plist in the same folder that i had created before, but i don't understand how configure it.
