+# CNCF sandbox project documentation primer
+
+This document is a quick primer for CNCF project maintainers and contributors
+who need to document their projects but don't know where to start. It provides a
+framework for thinking about user documentation that will enable the project
+contributors to write effective documentation from the very beginning and to get
+the most out of documentation efforts as the project matures.
+
+## What is "good" documentation?
+
+Documentation quality is ultimately measured by how _effective_ it is.
+
+The purpose of documentation is to help the user of a product achieve their
+objectives. The scope of these objectives ranges from individual tasks (use a
+command correctly, connect to a database) to large-scale goals (write a software
+product or module; configure a server farm). Objectives also vary by
+[user role](#product-users) (new developer; software architect; IT
+administrator).
+
+Documentation effectiveness, therefore, is defined by _how well it enables a
+user to succeed in achieving their objectives_, within every range of scope and
+for all users.
+
+### An information model for user documentation
+
+This discussion uses the following
+[model](https://www.lios.ca/en/blogue/concept-task-reference/) to categorize
+types of technical documentation.
+
+A documentation topic is one of these three types, depending on its purpose:
+
+- _Conceptual_ information describes one or more aspects of the project or its
+  products: its structure, purpose, motivation, architecture – almost anything.
+  Examples include:
+  - architectural overviews
+  - product histories
+  - technical white papers
+  - design discussions
+- _Task-based_ information describes how to do something. Examples include:
+  - procedure documentation, from individual task instructions to full
+    instruction manuals
+  - code "recipes" for creating particular software components
+  - specialized instructions such as troubleshooting guides
+  - learning materials such as tutorials
+- _Reference_ information is the "lookup" material specific to a product.
+  Examples include:
+  - API specifications
+  - command references
+  - knowledge bases
+  - user interface references
+  - error code lookups
+  - glossaries
+  - release notes
+
+### Descriptive vs. instructional documentation
+
+No type of information is "better" than any other. All three types are necessary
+to good technical documentation and should be present in the docs for any
+software product.
+
+That said, however, documentation writers involved with product development tend
+to write _descriptive_ documentation: they emphasize conceptual and reference
+information at the expense of task-based information.
+
+It's important, especially when developing a product, to describe what the
+product is designed to do. But in general, this does not make good user
+documentation. Descriptive documentation forces the user to search the
+documentation for a combination of features that will accomplish their goal,
+rather than being able to pursue that goal directly.
+
+Good software documentation is primarily _instructional_. The core of the
+documentation set aims to help users efficiently accomplish their goals. A
+traditional documentation set might contain a _getting started guide_ to help
+the user set up their workspace; _tutorials_ to teach skills and techniques; a
+_user guide_ (or _developer guide_) to explain and illustrate tools and
+workflows; and a _reference guide_ (often built into an IDE) to look up APIs,
+commands, or other toolkit components.
+
+Of course it's important that the documentation be feature-complete – that every
+capability of the product be documented. But it's equally important that every
+task that a user would reasonably want to perform be documented. A good cookbook
+doesn't just list ingredients, it tells you how to use them.
+
+## A process for developing user documentation
+
+So if starting with design documentation and expanding on the product's
+functionality isn't the best way to write user documentation, what is?
+
+Answer: To develop effective documentation it is necessary to describe the
+product's users and their objectives. This might seem like unnecessary extra
+work, but it will pay off very quickly in documentation quality.
+
+The rest of this document is a very brief description of a system for writing
+effective documentation for all of a product's users.
+
+### Product users
+
+First, define your product's _user roles_. A user role (also called a
+_persona_), is a type of user with a particular set of tasks they need to
+perform.
+
+As an example, consider a hypothetical product that consists of a REST API
+frontend to a server-based relational database. The user roles are:
+
+- _Developer_: Uses the REST API to list data records and perform CRUD
+  operations on the database.
+- _Administrator_: Sets up and maintains the product on one or more servers,
+  including a production server.
+
+For any OSS project, there are also these roles:
+
+- _Contributor_: A member of the project community who contributes code or other
+  labor to the project itself.
+- _Evaluator_: Someone who is considering using the product and needs to find
+  out more about it.
+
+One person can have multiple roles. For example, a contributor is often also a
+user (developer or admin, in this case).
+
+### Write goals
+
+Next, determine the goals of each user role that are served by the product. For
+the developer in the database example, a goal is probably to integrate the
+database into an end-user application.
+
+For the admin, a goal is to set up, say, a production and a test server and to
+populate them with identical data.
+
+### Develop tasks
+
+Analyze larger goals down to smaller ones. Ultimately, you want to get to the
+most basic unit of task-based documentation: discrete step-by-step tasks.
+
+#### Write for new users
+
+Pay special attention to the goals of new users.
+
+For example, new-user goals for developers always include:
+
+- Installing dependencies and software
+- Configuring a development environment
+- Running a "hello world" example or a similar simple task to verify the product
+
+When writing for new users (or indeed, any user who isn't part of the
+contributor community), try not to assume that the user knows anything about the
+product. This is especially true when writing task documentation.
+
+In the database example, say that configuring the server consists of copying the
+config file template to the config directory, setting permissions on the file,
+and editing the file to include the server IPs and some other parameters. Time
+and again we've seen configuration documentation that consists only of which
+config parameters to set. An effective configuration task, though, would walk
+through these steps:
+
+1. Copy the template from folder X to folder Y.
+1. Name the file Z.
+1. Set permissions on the file to ABC.
+1. Edit the file to set parameters Q, R, S and T. (And include a link to the
+   config reference\!)
+
+Don't worry about giving too much information. Novice users need it, and expert
+users will ignore it.
+
+### Support the task documentation
+
+Finally, support the task documentation with conceptual and reference
+documentation. The developer, for example, will need a complete reference for
+the REST API. The admin will need a complete description of every server
+configuration option. Both will need a reference for the CLI, if there is one.
+
+Conceptual information should always include a technical overview. This includes
+the product's purpose, architecture, and design rationales. This helps
+prospective users decide whether it's a solution for their problem, and helps
+advanced users reason about how to use or even extend its advanced features.
+
+## Nuts and bolts: deliverables and infrastructure
+
+### Required documentation
+
+A minimal documentation set varies by product, but some documents are (almost)
+always required to make the product usable:
+
+- A technical overview
+- A getting started guide
+- Reference manual(s)
+
+[Here's more](https://expertsupport.com/library/quick-and-easy-document-specifications/)
+on how to determine which docs you really need.
+
+### Where to put it
+
+At the sandbox stage, making the documentation available in some form is more
+important than hosting it in any particular place. That said, CNCF TechDocs has
+a [number of resources](https://github.com/cncf/techdocs/tree/main/docs) for
+creating web-based documentation.
+
+CNCF TechDocs can purchase, set up, and maintain your website's domain at no
+cost to your project. Contact CNCF TechDocs through the
+[CNCF TechDocs Service Desk](https://servicedesk.cncf.io) to request website
+hosting.
+
+Even if you don't use the CNCF recommended tools, it's worth reading the
+recommendations to preview the sorts of issues you'll encounter as the
+documentation matures. These issues parallel those facing the code
+infrastructure, and include things like scaling, hosting, versioning, indexing,
+SEO, and finding contributing writers.
+
+### What’s next
+
+For a thorough preparation in working with technical documentation, the
+following resources are available:
+
+[Open Source Documentation Essentials](https://training.linuxfoundation.org/training/open-source-technical-documentation-essentials-lfc111/)
+and
+[Creating Effective Documentation for Developers](https://training.linuxfoundation.org/training/creating-effective-documentation-for-developers-lfc112/)
+are free courses offered by CNCF and the Linux Foundation.
+
+[Google for Developers](https://developers.google.com) offers
+[free technical writing courses](https://developers.google.com/tech-writing).
+
+[Docs for Developers](https://docsfordevelopers.com/) is a guide to writing
+user-oriented documentation for software engineers.
