I suggested  because that's the typical installation here on Wikimedia foundation wikis, but you can use whatever path you want. Just don't use the same for $wgArticlePath, otherwise you won't be able to access articles that have the same title as files on the server (like index.php, README, HISTORY, images, etc), because of rewrite rules.
