Near the top of a wiki page is a tab. Or a few. One of those will take you to the text in edit mode and you simply type in your corrections.

Remember to make your edits whiter than white. It's the whole internet rage thing if you should dare be equal in your scorn as the original writer was luvey dovey.
That is the first Wikipedia page I've read which causes eyestrain and a headache. It reads like the crazy shit Cthulhu believers write.
