The .pdf and .doc versions of the docs have been removed from the official Tiki sources distribution since they were too big. You can download them from a separate package from SourceForge. Our SourceForge project URL is https://sourceforge.net/projects/tikiwiki. We also have a Tikiwiki site for the documentation, which is currently a work in progress available for reference at http://doc.tikiwiki.org It is highly recommended to read the docs to understand all the Tiki features and how to configure them. Thanks! Tikiwiki Community
