Technical documentation belongs on the web. Unless your product is top secret or your customers can’t access the Internet, you need to make an effort to get your content online. Doing so will greatly increase your customer’s ability to use the product while decreasing the amount of costly support calls made to your support engineers. But simply outputting your dry, stuffy manuals and guides into framed HTML or PDF isn’t enough anymore.
The landscape of documentation is changing. As with most things, change is inevitable. Documentation is not immune to that. Gone are the days of creating monolithic books that describe in detail every aspect of a piece of software.
