Manual is downloaded with the game but not linked to Steam

[Kianoni]

just a minor issue, you can easily find the "manual" (I would have called it an essay of the real manual) from within the steam folders but it should be accessible through steam.
- right click on COD from library
- select "Properties"
- Manual: [None available]

..please link it there so players don't have to google around some forums they've never heard of to be able to read this minimal information about the game.
