mockumentation

from Wiktionary, Creative Commons Attribution/Share-Alike License.

• noun slang Technical documentation such as user manuals, that assume the reader already knows the most obvious things they should be looking in the documentation to find, and therefore only mentions but never explains them (such as which port the client software uses to communicate with the server software). Instead it goes into great detail on the very obvious, such as the location of objects on the GUI, or how to click on the setup.exe file to install the application. Thus leaving the reader feeling insulted, stupid, and bitter.
