[Help with modng]

Hello,

 

I love mods and modding community so i decide to give it a shot. I have some good old games from 2000's and some RTS so i want to try and mod that. I want to try get better graphics and edit some models even add some gameplay cuz there is editor where u can create missions and adventures so if i mod details i can make some gameplay. Just i dont know where to start and how i can make those mods so if someone have free time to explain is there some programs to edit that things and what programming things need to do. Sorry for bad english and ty if u read this and reply :D
