We welcome community contributions to the documentation! You can help by reporting errors and typos, or by contributing new or updated sections. This topic describes the two main ways to contribute to the docs, and provides guidance on writing good documentation.

Two ways to improve the Puppet documentation

Filing a ticket

The Puppet documentation is managed like a software project, and you can file bug reports and feature requests in its issue tracker. You’ll need to create a JIRA account if you don’t already have one.

In your ticket, provide as much information as possible about what’s missing, what’s inaccurate, or what’s outdated. Include URLs to the affected pages. Describe your best understanding of what the documentation should say. We’ll begin looking into the problem, and you can follow our progress in the ticket.

Emailing us

If you spot a typo or other minor error and don’t want to go through the overhead of filing a ticket or editing the documentation, you can report it by email to

Puppet documentation guidelines

If you’d like to help contribute edits or new topics to the documentation, use these guidelines to create your content and then attach it when you file a ticket, either in the body of the ticket or as a separate markdown or text file.

Writing new topics from scratch

Each topic file should cover a single subject area. If the Puppet docs already have topics that discuss this area, modify those existing topics rather than creating a new one.

If you’re writing a new topic, start with an overview:

  • Provide definitions and descriptions that introduce the subject and place it within the context of the rest of Puppet.
  • Provide diagrams if they help clarify relationships and structures.
  • Your goal is to help people solve problems and get things done. Avoid too much background information.

Next, describe things that the person does:

  • Create a section for each major task that a person does. These should describe how to get results people want, not just things the tools require them to do.
  • List prerequisites, if any.
  • Use a numbered list to list the actions the person does to accomplish the task.
  • Finish by stating what the outcome is, and what the person might do next.
  • Provide code or command examples that show what to do for common scenarios.
  • If there are multiple ways of doing something, describe only one: the most straight-forward way for the given context.
  • Use screen captures minimally (ideally not at all), and only to illustrate things that are otherwise impractical to describe.
  • Avoid mixing lengthy conceptual descriptions in with task steps. Put those in your overview section instead.

For reference information for a command line tool or an API, follow the layout patterns in similar existing Puppet documentation. If this is lengthy, split it into its own Markdown file.

Provide links to related Puppet documentation topics, or other resources.

Updating existing documentation topics

Sometimes our docs are missing useful information that you can provide:

  • Basic-level concepts the original author took for granted, but are helpful for new people
  • Missing overviews, steps, or links
  • Missing prerequisites for tasks
  • Clarifying definitions for terms that Puppet is using differently than other technologies (for example, “class”)
  • Helpful code or command line examples
  • Troubleshooting tips


  • Strive to be friendly and authoritative.
  • Use simple, direct language. Avoid passive voice and implications.
  • Be consise, but not terse.
  • Use second-person almost always: “Open the file in your favorite text editor.”
  • Use inclusive, gender-neutral language.
  • Avoid patronizing language, often indicated by words like clearly, actually, or obviously.
  • Be honest but not negative about our product or competitors.

Grammar, idiom, and spelling

  • Metaphors, analogies, and certain turns of phrase might not translate into languages or cultures other than your own. Stick to comparisons that are relatively innocuous and universal.
  • Almost always, follow Associated Press (AP) Style and choose Webster’s dictionary spelling (American): color, specialize.
  • Use the serial comma. In a list with three or more items, include a comma after the second-last item, before the conjunction: “… is supported on Unix, Linux, and Windows.”


Use headings to increase the scanability of your content, and to make separate sections for conceptual information, each task, and reference information.

  • Nest H3s (markdown: ### ) inside H2s (## ). Nest H4s (#### ) inside H3s.
  • For conceptual information, use a noun phrase that accurately describes the content (for example, “Defined resource types”).
  • For task section headings, use a verb phrase that indicates the goal (for example, “Deploying your code”), but also differentiates it from other tasks (so maybe, “Deploying your code to a test environment”).


  • For file names and directories, use monospace.
  • When citing text that appears in the GUI, use bold.
  • For commands and code examples, use monospace. Short commands can be included as part of the paragraph. Longer examples or code should be set in a separate paragraph, enclosed within three tildes (~~~).
  • For user input on the command line, use monospace. For user input on a GUI, use italics.
  • To indicate text in code that should be replaced, use angle-brackets and all-caps (and, if in a code example, monospace): <TEST_HOSTNAME>
