Thread:Project:Support desk/How can I change the HTML title suffix of all the pages?

The suffix of pages in the English version of Wikipedia is " - Wikipedia, the free encyclopedia", how do I change the suffix to be different than the name of the website? My website is Speedypedia, still in alpha. I'm using the latest production versions of MediaWiki, PHP and MySQL - I don't know the version numbers, but you can see the source code of MediaWiki on GitHub.
