This is a DokuWiki install combined with a minimal Apache server preconfigured to run from an USB stick. The Apache/PHP setup is based on the MicroApache project.
This install comes with a precreated superuser. Login with admin/admin to access the DokuWiki administration backend. Be sure to change the password!
If you want to save some space on your stick you can delete languages you don't need from dokuwiki/inc/lang/ and dokuwiki/lib/plugins/*/lang/.
Have fun!
