article editing?

[GabbaGhoul]

Well I wanted to fix Mario's fireball physics.
And change Lucarios's aura ball into a fire ball.
I've posted requests for both of them before; but since no ones
jumping at the chance to help me out, I might as well learn to edit articles.
Problem is I have no Idea how and I don't know which program is used to do it.
Any input?
