What to include in GitLab documentation pages.

Documentation structure and template

This document will help you determine how to structure a page within GitLab's documentation and what content to include. These standards help ensure consistency and completeness throughout the documentation, and they make it easier to contribute.

Before getting started, familiarize yourself with GitLab's Documentation guidelines and the section on Content in the Style Guide.

Components of a documentation page

Most pages will be dedicated to a specific GitLab feature or to a use case that involves one or more features, potentially in conjunction with third-party tools.

Every feature or use case document should include the following content in the following sequence, with exceptions and details noted below and in the template included on this page.

  • Title: Top-level heading with the feature name, or a use case name, which would start with a verb, like "Configure", "Enable", and so on.
  • Introduction: A couple sentences about the subject matter and what's to be found on this page. Describe what the feature or topic is, what it does, and in what context it should be used. There is no need to add a title called "Introduction" or "Overview," because people rarely search for these terms. Just put this information after the title.
  • Use cases: describes real use case scenarios for that feature/configuration.
  • Requirements: describes what software, configuration, account, or knowledge is required.
  • Instructions: one or more sets of detailed instructions to follow.
  • Troubleshooting guide (recommended but not required).

For additional details on each, see the template for new docs, below.

Note that you can include additional subsections, as appropriate, such as 'How it Works', 'Architecture', and other logical divisions such as pre-deployment and post-deployment steps.

Template for new docs

To start a new document, respect the file tree and file name guidelines, as well as the style guidelines. Use the following template:

<!--Follow the Style Guide when working on this document.
https://docs.gitlab.com/ee/development/documentation/styleguide.html
When done, remove all of this commented-out text, except a commented-out
Troubleshooting section, which, if empty, can be left in place to encourage future use.-->
---
description: "Short document description." # Up to ~200 chars long. They will be displayed
in Google Search snippets. It may help to write the page intro first, and then reuse it here.
stage: "Add the stage name here, and remove the quotation marks"
group: "Add the group name here, and remove the quotation marks"
info: To determine the technical writer assigned to the Stage/Group associated with this page,
see https://about.gitlab.com/handbook/engineering/ux/technical-writing/#designated-technical-writers
---

# Feature Name or Use Case Name **[TIER]** (1)
<!--If writing about a use case, drop the tier, and start with a verb,
for example, "Configure", "Implement", + the goal/scenario-->

<!--For pages on newly-introduced features, add the following line.
If only some aspects of the feature have been introduced, specify which parts of the feature.-->
> [Introduced](link_to_issue_or_mr) in GitLab (Tier) X.Y (2).

An introduction -- without its own additional header -- goes here.
Offer a description of the feature or use case, and what to expect on this page.
(You can reuse this content, or part of it, for the front matter's `description` at the top
of this file).

The introduction should answer the following questions:

- What is this feature or use case?
- Who is it for?
- What is the context in which it is used and are there any prerequisites/requirements?
- What can the audience do with this? (Be sure to consider all applicable audiences, like
  GitLab admin and developer-user.)
- What are the benefits to using this over any alternatives?

## Use cases

Describe some use cases, typically in bulleted form. Include real-life examples for each.

If the page itself is dedicated to a use case, this section can usually include more specific
scenarios for use (for example, variations on the main use case), but if that's not applicable,
the section can be omitted.

Examples of use cases on feature pages:
- CE and EE: [Issues](../../user/project/issues/index.md#use-cases)
- CE and EE: [Merge Requests](../../user/project/merge_requests/index.md)
- EE-only: [Geo](../../administration/geo/replication/index.md)
- EE-only: [Jenkins integration](../../integration/jenkins.md)

## Requirements

State any requirements for using the feature and/or following along with the instructions.

These can include both:
- technical requirements (for example, an account on a third party service, an amount of storage space,
  prior configuration of another feature)
- prerequisite knowledge (for example, familiarity with certain GitLab features, cloud technologies)

Link each one to an appropriate place for more information.

## Instructions

This is the part of the document where you can include one or more sets of instructions.
Each topic should help users accomplish a specific task.

Headers should describe the task the reader will achieve by following the instructions within,
typically starting with a verb. For example, `Create a package` or `Configure a pipeline`.

Larger instruction sets may have subsections covering specific phases of the process.
Where appropriate, provide examples of code or configuration files to better clarify
intended usage.

- Write a step-by-step guide, with no gaps between the steps.
- Include example code or configurations as part of the relevant step.
  Use appropriate Markdown to wrap code blocks with
  [syntax highlighting](../../user/markdown.md#colored-code-and-syntax-highlighting).
- Start with an h2 (`##`), break complex steps into small steps using
  subheadings h3 > h4 > h5 > h6. _Never skip a hierarchy level, such
  as h2 > h4_, as it will break the TOC and may affect the breadcrumbs.
- Use short and descriptive headings (up to ~50 chars). You can use one
  single heading like `## Configure X` for instructions when the feature
  is simple and the document is short.

Example topic:

## Create a teddy bear

Start by writing a sentence or two about _why_ someone would want to perform this task.
It's not always possible, but is a good practice. For example:

Create a teddy bear when you need something to hug.

Follow this information with the task steps.

To create a teddy bear:

1. Go to **Settings > CI/CD**.
1. Expand **This** and click **This**.
1. Do another step.

After the numbered list, add a sentence with the expected result, if it
is not obvious, and any next steps. For example:

The teddy bear is now in the kitchen, in the cupboard above the sink.

You can retrieve the teddy bear and put it on the couch with the other animals.

Screenshots are not necessary. They are difficult to keep up-to-date and can clutter the page.

<!-- ## Troubleshooting

Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.

Each scenario can be a third-level heading, for example, `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->

Notes:

- (1): Apply the [tier badges](styleguide.md#product-badges) accordingly
- (2): Apply the correct format for the
       [GitLab version that introduces the feature](styleguide.md#gitlab-versions-and-tiers)

Help and feedback section

The "help and feedback" section (introduced by !319) displayed at the end of each document can be omitted from the doc by adding a key into the its front matter:

---
feedback: false
---

The default is to leave it there. If you want to omit it from a document, you must check with a technical writer before doing so.

Disqus

We also have integrated the docs site with Disqus (introduced by !151), allowing our users to post comments.

To omit only the comments from the feedback section, use the following key on the front matter:

---
comments: false
---

We are only hiding comments in main index pages, such as the main documentation index, since its content is too broad to comment on. Before omitting Disqus, you must check with a technical writer.

Note that once feedback: false is added to the front matter, it will automatically omit Disqus, therefore, don't add both keys to the same document.

The click events in the feedback section are tracked with Google Tag Manager. The conversions can be viewed on Google Analytics by navigating to Behavior > Events > Top events > docs.

Guidelines for good practices

Introduced in GitLab 13.2 as GitLab Development documentation.

"Good practice" examples demonstrate encouraged ways of writing code while comparing with examples of practices to avoid. These examples are labeled as "Bad" or "Good". In GitLab development guidelines, when presenting the cases, it is recommended to follow a first-bad-then-good strategy. First demonstrate the "Bad" practice (how things could be done, which is often still working code), and then how things should be done better, using a "Good" example. This is typically an improved example of the same code.

Consider the following guidelines when offering examples:

  • First, offer the "Bad" example, then the "Good" one.
  • When only one bad case and one good case is given, use the same code block.
  • When more than one bad case or one good case is offered, use separated code blocks for each. With many examples being presented, a clear separation helps the reader to go directly to the good part. Consider offering an explanation (for example, a comment, a link to a resource, etc.) on why something is bad practice.
  • Better and best cases can be considered part of the good case(s) code block. In the same code block, precede each with comments: # Better and # Best.

NOTE: Note: While the bad-then-good approach is acceptable for the GitLab development guidelines, do not use it for user documentation. For user documentation, use "Do" and "Don't." For example, see the Pajamas Design System.
