6 Preface Writing Guidelines

In general, you need the f

ollowing sections.

  1. About This Manual — orient the reader before they start. What type of document are they about to read? Is there anything out of scope in this release? What are the main chapter headings?
  2. Intended Audience — help the reader understand if this document is for beginners, experts, or particular functions, for example, security experts, C programmers, or network admins.
  3. Text Conventions — if you put something in bold, italic, or a special font, tell the reader what it means. This also helps other writers stay on track and avoid deviating from the style guide.
  4. New to this Release – for software updates, identify changes to the document. If the revision is extensive, list the changes by chapter.
  5. Acknowledgments – identify those who’ve helped you write the document, such as project sponsor, reviewers, designers, and others who’ve contributed.
  6. Related Documentation —what if the reader wants to learn more? Where should they go? It’s not enough to say, see the Admin Guide. Include a link to the Online Help or technical library where they can download the files.

If the revision is more modest, summarize the changes in paragraph form.

When describing changes, use a positive tone even if the deleted material was incorrect in the previous edition.


Include a list of people who’ve helped you write the document. Depending on the size and importance of the document, include reviewers, designers, and others who’ve contributed to the document’s development.

Other Documentation

Sample text you might use for this section:

The documents listed below are available in the Technical Library at

  • Getting Started – Introduces the software, including background information about prerequisites, standards, and installation instructions.
  • Integration Overview – Provides a high-level description of options available for integrating content management systems.
  • Clustering Guide – Describes how to deploy content management systems in a cluster to increase availability.
  • Online Resources – We continually updates our Resource Center ( with technical information, white papers, demonstrations, webinars, and other resources.


Not every document needs a preface, so don’t feel compelled to write a preface for every user manual, installation guide, or business plan.

It’s a judgement call.

Not sure?

Ask yourself:

Would a preface help my reader understand the scope of this document?

If so, create a nice short preface. See if it helps.
