--- ## Remarks
+-- ## How To Use Your Own Voice Overs
+-- 
+-- If you have a set of AIRBOSS sound files recorded or got it from elsewhere it is possible to use those instead of the default ones.
+-- I recommend to use exactly the same file names as the original sound files have.
+-- 
+-- However, the **timing is critical**! As sometimes sounds are played directly after one another, e.g. by saying the modex but also on other occations, the airboss
+-- script has a radio queue implemented (actually two - one for the LSO and one for the Marshal/Airboss radio).
+-- By this it is automatically taken care that played messages are not overlapping and played over each other. The disadvantage is, that the script needs to know
+-- the exact duration of *each* voice over. For the default sounds this is hard coded in the source code. For your own files, you need to give that bit of information
+-- to the script via the @{#AIRBOSS.SetVoiceOver}(**radiocall**, **duration**, **subtitle**, **subduration**, **filename**, **suffix**) function. Only the first two 
+-- parameters **radiocall** and **duration** are usually important to adjust here.
+-- 
+-- For example, if you want to change the LSO "Call the Ball" and "Roger Ball" calls:
+-- 
+--     airbossStennis:SetVoiceOver(airbossStennis.LSOCall.CALLTHEBALL, 0.6)
+--     airbossStennis:SetVoiceOver(airbossStennis.LSOCall.ROGERBALL, 0.7)
+--     
+-- Again, changing the file name, subtitle, subtitle duration is not required if you name the file exactly like the original one, which is this case would be "LSO-RogerBall.ogg".
+--     
+-- ## Carrier Specific Voice Overs
+-- 
+-- It is possible to use diffent sound files for different carriers. If you have set up two (or more) AIRBOSS objects at different carriers - say Stennis and Tarawa - each
+-- carrier would use the files in the specified directory, e.g.
+-- 
+--     airbossStennis:SetSoundfilesFolder("Airboss Soundfiles Stenis/")
+--     airbossTarawa:SetSoundfilesFolder("Airboss Soundfiles Tarawa/")
