# Documentation style guidelines
The documentation style guide defines the markup structure used in
GitLab documentation. Check the
[documentation guidelines](index.md) for general development instructions.
Check the GitLab handbook for the [writing styles guidelines](https://about.gitlab.com/handbook/communication/#writing-style-guidelines).
For help adhering to the guidelines, see [linting](index.md#linting).
## Files
- [Directory structure](index.md#location-and-naming-documents): place the docs
in the correct location.
- [Documentation files](index.md#documentation-files): name the files accordingly.
DANGER: **Attention:**
**Do not** use capital letters, spaces, or special chars in file names,
branch names, directory names, headings, or in anything that generates a path.
NOTE: **Note:**
**Do not** create new `README.md` files, name them `index.md` instead. There's
a test that will fail if it spots a new `README.md` file.
### Markdown
The [documentation website](https://docs.gitlab.com) had its markdown engine migrated from [Redcarpet to GitLab Kramdown](https://gitlab.com/gitlab-com/gitlab-docs/merge_requests/108)
in October, 2018.
The [`gitlab-kramdown`](https://gitlab.com/gitlab-org/gitlab_kramdown)
gem will support all [GFM markup](../../user/markdown.md) in the future. For now,
use regular markdown markup, following the rules on this style guide. For a complete
Kramdown reference, check the [GiLab Markdown Kramdown Guide](https://about.gitlab.com/handbook/product/technical-writing/markdown-guide/).
Use Kramdown markup wisely: do not overuse its specific markup (e.g., `{:.class}`) as it will not render properly in
[`/help`](#gitlab-help).
## Content
- Make sure that the documentation is added in the correct
[directory](index.md#documentation-directory-structure), linked from its
higher-level index, and linked from other related pages.
- Do not duplicate information.
- Be brief and clear.
- Unless there's a logical reason not to, structure the document in alphabetical order
(headings, tables, and lists).
- Write in US English.
- Capitalize "G" and "L" in GitLab.
- Use title case when referring to [features](https://about.gitlab.com/features/) or
[products](https://about.gitlab.com/pricing/) (e.g., GitLab Runner, Geo,
Issue Boards, GitLab Core, Git, Prometheus, Kubernetes, etc), and methods or methodologies
(e.g., Continuous Integration, Continuous Deployment, Scrum, Agile, etc). Note that
some features are also objects (e.g. "GitLab's Merge Requests support X." and "Create a new merge request for Z.").
## Text
- Split up long lines (wrap text), this makes it much easier to review and edit. Only
double line breaks are shown as a full line break by creating new paragraphs.
80-100 characters is the recommended line length.
- Use sentence case for titles, headings, labels, menu items, and buttons.
- Jump a line between different markups (e.g., after every paragraph, header, list, etc). Example:
```md
## Header
Paragraph.
- List item 1
- List item 2
```
## Emphasis
- Use double asterisks (`**`) to mark a word or text in bold (`**bold**`).
- Use undescore (`_`) for text in italics (`_italic_`).
- Use greater than (`>`) for blockquotes.
## Punctuation
Check the general punctuation rules for the GitLab documentation on the table below.
Check specific punctuation rules for [list items](#list-items) below.
| Rule | Example |
| ---- | ------- |
| Always end full sentences with a period. | _For a complete overview, read through this document._|
| Always add a space after a period when beginning a new sentence | _For a complete overview, check this doc. For other references, check out this guide._ |
| Do not use double spaces. | --- |
| Do not use tabs for indentation. Use spaces instead. You can configure your code editor to output spaces instead of tabs when pressing the tab key. | --- |
| Use serial commas ("Oxford commas") before the final 'and/or' in a list. | _You can create new issues, merge requests, and milestones._ |
| Always add a space before and after dashes when using it in a sentence (for replacing a comma, for example). | _You should try this - or not._ |
| Always use lowercase after a colon. | _Related Issues: a way to create a relationship between issues._ |
## List items
- Always start list items with a capital letter.
- Always leave a blank line before and after a list.
- Begin a line with spaces (not tabs) to denote a subitem.
- To nest subitems, indent them with two spaces.
- To nest code blocks, indent them with four spaces.
- Only use ordered lists when their items describe a sequence of steps to follow.
**Markup:**
- Use dashes (`- `) for unordered lists instead of asterisks (`* `).
- Use the number one (`1`) for each item in an ordered list.
When rendered, the list items will appear with sequential numbering.
**Punctuation:**
- Do not add commas (`,`) or semicolons (`;`) to the end of a list item.
- Only add periods to the end of a list item if the item consists of a complete sentence. The [definition of full sentence](https://www2.le.ac.uk/offices/ld/resources/writing/grammar/grammar-guides/sentence) is: _"a complete sentence always contains a verb, expresses a complete idea, and makes sense standing alone"_.
- Be consistent throughout the list: if the majority of the items do not end in a period, do not end any of the items in a period, even if they consist of a complete sentence. The opposite is also valid: if the majority of the items end with a period, end all with a period.
- Separate list items from explanatory text with a colon (`:`). For example:
```md
The list is as follows:
- First item: this explains the first item.
- Second item: this explains the second item.
```
**Examples:**
Do:
- First list item
- Second list item
- Third list item
Don't:
- First list item
- Second list item
- Third list item.
Do:
- Let's say this is a complete sentence.
- Let's say this is also a complete sentence.
- Not a complete sentence.
Don't:
- Let's say this is a complete sentence.
- Let's say this is also a complete sentence.
- Not a complete sentence
## Quotes
Valid for markdown content only, not for frontmatter entries:
- Standard quotes: double quotes (`"`). Example: "This is wrapped in double quotes".
- Quote within a quote: double quotes (`"`) wrap single quotes (`'`). Example: "I am 'quoting' something within a quote".
For other punctuation rules, please refer to the
[GitLab UX guide](https://design.gitlab.com/content/punctuation/).
## Headings
- Add **only one H1** in each document, by adding `#` at the beginning of
it (when using markdown). The `h1` will be the document `<title>`.
- Start with an `h2` (`##`), and respect the order `h2` > `h3` > `h4` > `h5` > `h6`.
Never skip the hierarchy level, such as `h2` > `h4`
- Avoid putting numbers in headings. Numbers shift, hence documentation anchor
links shift too, which eventually leads to dead links. If you think it is
compelling to add numbers in headings, make sure to at least discuss it with
someone in the Merge Request.
- [Avoid using symbols and special chars](https://gitlab.com/gitlab-com/gitlab-docs/issues/84)
in headers. Whenever possible, they should be plain and short text.
- Avoid adding things that show ephemeral statuses. For example, if a feature is
considered beta or experimental, put this info in a note, not in the heading.
- When introducing a new document, be careful for the headings to be
grammatically and syntactically correct. Mention an [assigned technical writer (TW)](https://about.gitlab.com/handbook/product/categories/)
for review.
This is to ensure that no document with wrong heading is going
live without an audit, thus preventing dead links and redirection issues when
corrected.
- Leave exactly one new line after a heading.
- Do not use links in headings.
- Add the corresponding [product badge](#product-badges) according to the tier the feature belongs.
## Links
- Use inline link markdown markup `[Text](https://example.com)`.
It's easier to read, review, and maintain. **Do not** use `[Text][identifier]`.
- To link to internal documentation, use relative links, not full URLs. Use `../` to
navigate tp high-level directories, and always add the file name `file.md` at the
end of the link with the `.md` extension, not `.html`.
Example: instead of `[text](../../merge_requests/)`, use
`[text](../../merge_requests/index.md)` or, `[text](../../ci/README.md)`, or,
for anchor links, `[text](../../ci/README.md#examples)`.
Using the markdown extension is necessary for the [`/help`](index.md#gitlab-help)
section of GitLab.
- To link from CE to EE-only documentation, use the EE-only doc full URL.
- Use [meaningful anchor texts](https://www.futurehosting.com/blog/links-should-have-meaningful-anchor-text-heres-why/).
E.g., instead of writing something like `Read more about GitLab Issue Boards [here](LINK)`,
write `Read more about [GitLab Issue Boards](LINK)`.
## Navigation
To indicate the steps of navigation through the UI:
- Use the exact word as shown in the UI, including any capital letters as-is.
- Use bold text for navigation items and the char "greater than" (`>`) as separator
(e.g., `Navigate to your project's **Settings > CI/CD**` ).
- If there are any expandable menus, make sure to mention that the user
needs to expand the tab to find the settings you're referring to (e.g., `Navigate to your project's **Settings > CI/CD** and expand **General pipelines**`).
## Images
- Place images in a separate directory named `img/` in the same directory where
the `.md` document that you're working on is located. Always prepend their
names with the name of the document that they will be included in. For
example, if there is a document called `twitter.md`, then a valid image name
could be `twitter_login_screen.png`.
- Images should have a specific, non-generic name that will differentiate and describe them properly.
- Keep all file names in lower case.
- Consider using PNG images instead of JPEG.
- Compress all images with <https://tinypng.com/> or similar tool.
- Compress gifs with <https://ezgif.com/optimize> or similar tool.
- Images should be used (only when necessary) to _illustrate_ the description
of a process, not to _replace_ it.
- Max image size: 100KB (gifs included).
- The GitLab docs do not support videos yet.
Inside the document:
- The Markdown way of using an image inside a document is:
`![Proper description what the image is about](img/document_image_title.png)`
- Always use a proper description for what the image is about. That way, when a
browser fails to show the image, this text will be used as an alternative
description.
- If there are consecutive images with little text between them, always add
three dashes (`---`) between the image and the text to create a horizontal
line for better clarity.
- If a heading is placed right after an image, always add three dashes (`---`)
between the image and the heading.
## Code blocks
- Always wrap code added to a sentence in inline code blocks (``` ` ```).
E.g., `.gitlab-ci.yml`, `git add .`, `CODEOWNERS`, `only: master`.
File names, commands, entries, and anything that refers to code should be added to code blocks.
To make things easier for the user, always add a full code block for things that can be
useful to copy and paste, as they can easily do it with the button on code blocks.
- For regular code blocks, always use a highlighting class corresponding to the
language for better readability. Examples:
```md
```ruby
Ruby code
```
```js
JavaScript code
```
```md
Markdown code
```
```
- For a complete reference on code blocks, check the [Kramdown guide](https://about.gitlab.com/handbook/product/technical-writing/markdown-guide/#code-blocks).
## Alert boxes
Whenever you want to call the attention to a particular sentence,
use the following markup for highlighting.
_Note that the alert boxes only work for one paragraph only. Multiple paragraphs,
lists, headers, etc will not render correctly. For multiple lines, use blockquotes instead._
### Note
```md
NOTE: **Note:**
This is something to note.
```
How it renders in docs.gitlab.com:
NOTE: **Note:**
This is something to note.
### Tip
```md
TIP: **Tip:**
This is a tip.
```
How it renders in docs.gitlab.com:
TIP: **Tip:**
This is a tip.
### Caution
```md
CAUTION: **Caution:**
This is something to be cautious about.
```
How it renders in docs.gitlab.com:
CAUTION: **Caution:**
This is something to be cautious about.
### Danger
```md
DANGER: **Danger:**
This is a breaking change, a bug, or something very important to note.
```
How it renders in docs.gitlab.com:
DANGER: **Danger:**
This is a breaking change, a bug, or something very important to note.
## Blockquotes
For highlighting a text within a blue blockquote, use this format:
```md
> This is a blockquote.
```
which renders in docs.gitlab.com to:
> This is a blockquote.
If the text spans across multiple lines it's OK to split the line.
For multiple paragraphs, use the symbol `>` before every line:
```md
> This is the first paragraph.
>
> This is the second paragraph.
>
> - This is a list item
> - Second item in the list
>
> ### This is an `h3`
```
Which renders to:
> This is the first paragraph.
>
> This is the second paragraph.
>
> - This is a list item
> - Second item in the list
>
> ### This is an `h3`
>{:.no_toc}
## Specific sections and terms
To mention and/or reference specific terms in GitLab, please follow the styles
below.
### GitLab versions and tiers
- Every piece of documentation that comes with a new feature should declare the
GitLab version that feature got introduced. Right below the heading add a
blockquote:
```md
> Introduced in GitLab 8.3.
```
- Whenever possible, every feature should have a link to the issue, MR or epic
(in that order) that introduced it. The above quote would be then transformed to:
```md
> [Introduced](<link-to-issue>) in GitLab 8.3.
```
- If the feature is only available in GitLab Enterprise Edition, don't forget to mention
the [paid tier](https://about.gitlab.com/handbook/marketing/product-marketing/#tiers)
the feature is available in:
```md
> [Introduced](<link-to-issue>) in [GitLab Starter](https://about.gitlab.com/pricing/) 10.3.
```
#### Early versions of EE
If the feature was created before GitLab 9.2 (before [different EE tiers were introduced](https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/1851)):
- Declare it as "Introduced in GitLab Enterprise Edition X.Y".
- Note which tier the feature is available in.
For example:
```md
> [Introduced](<link-to-issue>) in GitLab Enterprise Edition 9.0. Available in [GitLab Premium](https://about.gitlab.com/pricing/).
```
### Product badges
When a feature is available in EE-only tiers, add the corresponding tier according to the
feature availability:
- For GitLab Starter and GitLab.com Bronze: `**[STARTER]**`.
- For GitLab Premium and GitLab.com Silver: `**[PREMIUM]**`.
- For GitLab Ultimate and GitLab.com Gold: `**[ULTIMATE]**`.
- For GitLab Core and GitLab.com Free: `**[CORE]**`.
To exclude GitLab.com tiers (when the feature is not available in GitLab.com), add the
keyword "only":
- For GitLab Core: `**[CORE ONLY]**`.
- For GitLab Starter: `**[STARTER ONLY]**`.
- For GitLab Premium: `**[PREMIUM ONLY]**`.
- For GitLab Ultimate: `**[ULTIMATE ONLY]**`.
The tier should be ideally added to headers, so that the full badge will be displayed.
However, it can be also mentioned from paragraphs, list items, and table cells. For these cases,
the tier mention will be represented by an orange question mark that will show the tiers on hover.
E.g., `**[STARTER]**` renders **[STARTER]**, `**[STARTER ONLY]**` renders **[STARTER ONLY]**.
The absence of tiers' mentions mean that the feature is available in GitLab Core,
GitLab.com Free, and all higher tiers.
#### How it works
Introduced by [!244](https://gitlab.com/gitlab-com/gitlab-docs/merge_requests/244),
the special markup `**[STARTER]**` will generate a `span` element to trigger the
badges and tooltips (`<span class="badge-trigger starter">`). When the keyword
"only" is added, the corresponding GitLab.com badge will not be displayed.
### GitLab Restart
There are many cases that a restart/reconfigure of GitLab is required. To
avoid duplication, link to the special document that can be found in
[`doc/administration/restart_gitlab.md`][doc-restart]. Usually the text will
read like:
```md
Save the file and [reconfigure GitLab](../../administration/restart_gitlab.md)
for the changes to take effect.
```
If the document you are editing resides in a place other than the GitLab CE/EE
`doc/` directory, instead of the relative link, use the full path:
`http://docs.gitlab.com/ce/administration/restart_gitlab.html`.
Replace `reconfigure` with `restart` where appropriate.
### Installation guide
**Ruby:**
In [step 2 of the installation guide](../../install/installation.md#2-ruby),
we install Ruby from source. Whenever there is a new version that needs to
be updated, remember to change it throughout the codeblock and also replace
the sha256sum (it can be found in the [downloads page][ruby-dl] of the Ruby
website).

### Configuration documentation for source and Omnibus installations
GitLab currently officially supports two installation methods: installations
from source and Omnibus packages installations.
Whenever there is a setting that is configurable for both installation methods,
prefer to document it in the CE docs to avoid duplication.
Configuration settings include:
1. Settings that touch configuration files in `config/`.
1. NGINX settings and settings in `lib/support/` in general.
When there is a list of steps to perform, usually that entails editing the
configuration file and reconfiguring/restarting GitLab. In such case, follow
the style below as a guide:
```md
**For Omnibus installations**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
external_url "https://gitlab.example.com"
```
1. Save the file and [reconfigure] GitLab for the changes to take effect.
---
**For installations from source**
1. Edit `config/gitlab.yml`:
```yaml
gitlab:
host: "gitlab.example.com"
```
1. Save the file and [restart] GitLab for the changes to take effect.
[reconfigure]: path/to/administration/restart_gitlab.md#omnibus-gitlab-reconfigure
[restart]: path/to/administration/restart_gitlab.md#installations-from-source
```
In this case:
- Before each step list the installation method is declared in bold
- Three dashes (`---`) are used to create a horizontal line and separate the
two methods
- The code blocks are indented one or more spaces under the list item to render
correctly
- Different highlighting languages are used for each config in the code block
- The [references](#references) guide is used for reconfigure/restart
### Fake tokens
There may be times where a token is needed to demonstrate an API call using
cURL or a variable used in CI. It is strongly advised not to use real
tokens in documentation even if the probability of a token being exploited is
low.
You can use the following fake tokens as examples.
| **Token type** | **Token value** |
|:----------------------|:-------------------------------------------------------------------|
| Private user token | `9koXpg98eAheJpvBs5tK` |
| Personal access token | `n671WNGecHugsdEDPsyo` |
| Application ID | `2fcb195768c39e9a94cec2c2e32c59c0aad7a3365c10892e8116b5d83d4096b6` |
| Application secret | `04f294d1eaca42b8692017b426d53bbc8fe75f827734f0260710b83a556082df` |
| CI/CD variable | `Li8j-mLUVA3eZYjPfd_H` |
| Specific Runner token | `yrnZW46BrtBFqM7xDzE7dddd` |
| Shared Runner token | `6Vk7ZsosqQyfreAxXTZr` |
| Trigger token | `be20d8dcc028677c931e04f3871a9b` |
| Webhook secret token | `6XhDroRcYPM5by_h-HLY` |
| Health check token | `Tu7BgjR9qeZTEyRzGG2P` |
| Request profile token | `7VgpS4Ax5utVD2esNstz` |
### API
Here is a list of must-have items. Use them in the exact order that appears
on this document. Further explanation is given below.
- Every method must have the REST API request. For example:
```
GET /projects/:id/repository/branches
```
- Every method must have a detailed
[description of the parameters](#method-description).
- Every method must have a cURL example.
- Every method must have a response body (in JSON format).
#### Method description
Use the following table headers to describe the methods. Attributes should
always be in code blocks using backticks (``` ` ```).
```md
| Attribute | Type | Required | Description |
|:----------|:-----|:---------|:------------|
```
Rendered example:
| Attribute | Type | Required | Description |
|:----------|:-------|:---------|:--------------------|
| `user` | string | yes | The GitLab username |
#### cURL commands
- Use `https://gitlab.example.com/api/v4/` as an endpoint.
- Wherever needed use this personal access token: `9koXpg98eAheJpvBs5tK`.
- Always put the request first. `GET` is the default so you don't have to
include it.
- Use double quotes to the URL when it includes additional parameters.
- Prefer to use examples using the personal access token and don't pass data of
username and password.
| Methods | Description |
|:-------------------------------------------|:------------------------------------------------------|
| `-H "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK"` | Use this method as is, whenever authentication needed |
| `-X POST` | Use this method when creating new objects |
| `-X PUT` | Use this method when updating existing objects |
| `-X DELETE` | Use this method when removing existing objects |
#### cURL Examples
Below is a set of [cURL][] examples that you can use in the API documentation.
##### Simple cURL command
Get the details of a group:
```bash
curl --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v4/groups/gitlab-org
```
##### cURL example with parameters passed in the URL
Create a new project under the authenticated user's namespace:
```bash
curl --request POST --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" "https://gitlab.example.com/api/v4/projects?name=foo"
```
##### Post data using cURL's --data
Instead of using `-X POST` and appending the parameters to the URI, you can use
cURL's `--data` option. The example below will create a new project `foo` under
the authenticated user's namespace.
```bash
curl --data "name=foo" --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" "https://gitlab.example.com/api/v4/projects"
```
##### Post data using JSON content
> **Note:** In this example we create a new group. Watch carefully the single
and double quotes.
```bash
curl --request POST --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" --header "Content-Type: application/json" --data '{"path": "my-group", "name": "My group"}' https://gitlab.example.com/api/v4/groups
```
##### Post data using form-data
Instead of using JSON or urlencode you can use multipart/form-data which
properly handles data encoding:
```bash
curl --request POST --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" --form "title=ssh-key" --form "key=ssh-rsa AAAAB3NzaC1yc2EA..." https://gitlab.example.com/api/v4/users/25/keys
```
The above example is run by and administrator and will add an SSH public key
titled ssh-key to user's account which has an id of 25.
##### Escape special characters
Spaces or slashes (`/`) may sometimes result to errors, thus it is recommended
to escape them when possible. In the example below we create a new issue which
contains spaces in its title. Observe how spaces are escaped using the `%20`
ASCII code.
```bash
curl --request POST --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" "https://gitlab.example.com/api/v4/projects/42/issues?title=Hello%20Dude"
```
Use `%2F` for slashes (`/`).
##### Pass arrays to API calls
The GitLab API sometimes accepts arrays of strings or integers. For example, to
restrict the sign-up e-mail domains of a GitLab instance to `*.example.com` and
`example.net`, you would do something like this:
```bash
curl --request PUT --header "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" --data "domain_whitelist[]=*.example.com" --data "domain_whitelist[]=example.net" https://gitlab.example.com/api/v4/application/settings
```
