Things to replace - ALL_CAPITAL_WORDS:

1. PATH_TO_AIR_SDK_FOLDER
2. CERTIFICATE_FOLDER
3. RELEASE_FOLDER
4. APPLICATION_NAME
5. MAIN_CLASS
6. COM_APPLICATION_ID
7. KEY_PASS
   and of course IP

I suggest that your main class has the same name as output .swf file

<initialWindow>
    <content>MAIN_CLASS.swf</content>
    <renderMode>direct</renderMode>
    ...
</initialWindow>

And you have icons in a folder

<icon>
    <image40x40>icons/icon_40.png</image40x40>
    <image48x48>icons/icon_48.png</image48x48>
    <image57x57>icons/icon_57.png</image57x57>
...
</icon>
