Help Making (and referencing) New Grenade Sound

[Big Beej 2]

Hi, first post / absolute modding novice here, but I've got ~1k hours on messing with Arma 3. I have an okay understanding how the config.cpp file should be formatted, how it works, etc.

What I'm trying to do is create a new grenade object (using the base classes, of course), and define a custom sound for it. All I have right now is a functional retexture, with the following definition:

class CfgVehicles
{
    class RGD5Grenade;
    class My_Grenade: RGD5Grenade
    {
        scope=2;
        displayName="FisherPrice_MyFirstGrenade";
        descriptionShort="Possibly dangerous";
        model="MyMod\frag_RGD5.p3d";

        hiddenSelectionsTextures[]=
        {
            "MyMod\frag_retexture_CO.paa"
        };

    };
};
 

I somewhat understand how sound tails, shaders and sets work from my Arma 3 experience, but I cannot begin to comprehend how to functionally integrate them into my config.cpp. I would greatly appreciate if someone more knowledgeable could do any of the following:

1. Point out / link the relevant wiki page(s)

2. Explain how to define and reference a SoundSet

3. Finish my garbage code for me, and I'll make sense of it myself. 

Thanks in advance!
