User Guide: helping clients, attracting prospects
Technical documentation is notoriously known as something of no use when you try to start your brand new vacuum cleaner. Though it is seldom regarded as a marketing tool, user guides are the documents clients read the most.
Sales engineers often use user guides as a sales argument, if the technical documentation takes into account pre-sales. Within the company, technical documentation then changes its status from a costly after-sales service to an efficient marketing tool.

The technical level of a user guide depends on the technical expertise of its audience. But a good user guides is always as simple as possible.
