The army generator is actually just an Excel worksheet with a lot of pre-entered information and tables. It has different sections for characters, squads and support, as well as a handy reference to most wargear cards (at least those directly useful to a Space Marines army). The point costs for most characters, squads, vehicles, and their most common upgrades are also listed. As I based the army generator on the Ultramarines Codex, it will only support a standard Codex chapter - not Blood Angels or Space Wolves.
I think the biggest advantage when using this, is that you can very easily keep track of the point values of the different sections of the army. It also allows you to change the weaponry, vehicles, characters and so on, over and over again without a lot of writing and erasing. When you are happy with the final result, just write it down on a sheet of paper (or print it). And last but not least, it is a breeze to use an old army that performed well, and change the parts of it that didn't.
The short, short version of the manual
The red text is calculated point values, don't touch them. The blue fields are for entering wargear, names, point costs etc. Note that no fields are write protected, so you might lose something if you're not careful.
