I found where are these lua files, they are in 'pathToGame/gamedata/lua.scd and you have to open lua.scd via winRAR or smth else

For example

local Objectives = import('/lua/ScenarioFramework.lua').Objectives
local ScenarioFramework = import('/lua/ScenarioFramework.lua')
local ScenarioPlatoonAI = import('/lua/ScenarioPlatoonAI.lua')
local ScenarioUtils = import('/lua/sim/ScenarioUtilities.lua')
local Utilities = import('/lua/utilities.lua')

where from these ScenarioFramework.lua, ScenarioUtilities.lua etc?
Or atleast where is nice documentation that explains what any function does and which functions do even exist?

I am just new to scripting so I don't know much.
