To many people, when you say "wiki", what comes to mind is "Wikipedia", since this is probably the most well-known wiki on the Internet. Wikipedia is great, but the MediaWiki software that powers it isn't the best solution for every wiki website, especially for what might be called a "wiki plus" (see https://www.mediawiki.org/wiki/Manual:What_is_MediaWiki%3F#Some_things_MediaWiki_doesn.27t_do_so_well...). And, unlike Mediawiki sites, Tikipedia on Tiki implements responsive web design - a single HTML page for all device sizes - so there's no need for a separate mobile site. For websites where the well-known Wikipedia layout and appearance would be appropriate, but that need more features and power than MediaWiki provides, the Tikipedia theme is now available for Tiki Wiki CMS Groupware.
Not every detail is identical. Low-level template file customization and so on was avoided in order to ensure continuing compatibility with the Tiki software and easy version updates. But overall the visual similarity is pretty close.
MediaWiki site administrators and editors will find that Tiki uses some different wiki syntax and page elements, so there will be a bit of a learning curve. There is a migration script to bring MediaWiki content into a Tiki site, available since Tiki 4, but current functionality should be checked.
Beyond the wiki, Tiki of course has a range of other features including blogs, galleries, "tracker" database functionality, and so on, so a Tikipedia site will really be a "wiki plus".
As with other "add-on" themes, just put the unzipped Tikipedia directory into the themes directory. Directory access permissions (chmod) may need to be set similar to those of the other theme directories. Then reload tiki-admin.php?page=look, to find Tikipedia in the list of available themes.
Absolute positioning is used to place the menu (class="tikipedia_menu") at the bottom of the topbar module zone. The other modules in the topbar zone are configured normally except for being floated right, to reflect the MediaWiki positioning.
This theme doesn't try to replicate every MediaWiki Vector theme page detail - a balance was struck between similar appearance and ease of maintaining the theme. No Smarty template changes were made; Tikipedia uses only CSS and standard Tiki site configuration to attain this layout and appearance.
