MediaWiki Problem

I've just installed MediaWiki fine on one of my domains, just one problem.

It says you have to change the image path of

$wgLogo

To your desired image path of your own logo to set it.

But I cannot find '$wgLogo' in the LocalSettings.php?

 

Try
includes/DefaultSettings.php

 

It says never to edit that file.

 

I dont think it is in localsettings.php by default. You would have to make it.

 

i put the line in on localsettings.php because I thought that but then got an error when trying to load the site

 

I have this in my localsettings.php: $wgLogo = "logo.png";
Edit: At the bottom

 

I don't have that on mine...

 

I added it my self
