I want to customize the navigation bar, and the user guide tells me the following
"The contents of the navigation bar which appears to the left of each page using the Monobook skin are determined by the MediaWiki:Sidebar page. For information on customising these, please see Manual:Navigation bar."
I am having trouble understanding what do they mean by “MediaWiki:Sidebar page.” How do I get to this page on my wiki? When I click the link in this statement, it takes me to the mediawiki.org’s MediaWiki’s Sidebar page. I am having trouble finding the page on my site where I could edit the navigation bar.
