Your wiki wordmark is probably one of the first things your visitors will see. Therefore, it should best match the rest of the layout of your wiki, as well as to some extent represent the wiki content; girly wikis might contain curly letters whereas gaming wikis might match the game name's color and font.

In order to change the wordmark, you first need to go to your wiki's Special:ThemeDesigner page. You can do this either directly in the URL bar or by accessing it through the admin panel. From there, simply upload a new image from there and hit Save!
