Literate User Interface

I have been writing a user guide for the data entry section of a website.
I had copied some of the links from the site into the document.

One of the users mentioned that is the userguide available on the website?
That got me thinking – why not embed the user interface for infrequently used code into the user manual?
The users will not fail to find the documentation and it will encourage the developer to keep the documentation upto date.
