-# Documentation styleguide
+# Documentation style guidelines
 
-This styleguide recommends best practices to improve documentation and to keep
-it organized and easy to find.
+The documentation style guide defines the markup structure used in
+GitLab documentation. Check the
+[documentation guidelines](writing_documentation.md) for general development instructions.
 
-See also [writing documentation](writing_documentation.md).
-
-## Location and naming of documents
-
->**Note:**
-These guidelines derive from the discussion taken place in issue [#3349][ce-3349].
-
-The documentation hierarchy can be vastly improved by providing a better layout
-and organization of directories.
-
-Having a structured document layout, we will be able to have meaningful URLs
-like `docs.gitlab.com/user/project/merge_requests.html`. With this pattern,
-you can immediately tell that you are navigating a user related documentation
-and is about the project and its merge requests.
-
-Do not create summaries of similar types of content (e.g. an index of all articles, videos, etc.),
-rather organise content by its subject (e.g. everything related to CI goes together)
-and cross-link between any related content.
-
-The table below shows what kind of documentation goes where.
-
-| Directory | What belongs here |
-| --------- | -------------- |
-| `doc/user/` | User related documentation. Anything that can be done within the GitLab UI goes here including `/admin`. |
-| `doc/administration/`  | Documentation that requires the user to have access to the server where GitLab is installed. The admin settings that can be accessed via GitLab's interface go under `doc/user/admin_area/`. |
-| `doc/api/` | API related documentation. |
-| `doc/development/` | Documentation related to the development of GitLab. Any styleguides should go here. |
-| `doc/legal/` | Legal documents about contributing to GitLab. |
-| `doc/install/`| Probably the most visited directory, since `installation.md` is there. Ideally this should go under `doc/administration/`, but it's best to leave it as-is in order to avoid confusion (still debated though). |
-| `doc/update/` | Same with `doc/install/`. Should be under `administration/`, but this is a well known location, better leave as-is, at least for now. |
-| `doc/topics/` | Indexes per Topic (`doc/topics/topic-name/index.md`): all resources for that topic (user and admin documentation, articles, and third-party docs) |
-

-
-**General rules:**
-
-1. The correct naming and location of a new document, is a combination
-   of the relative URL of the document in question and the GitLab Map design
-   that is used for UX purposes ([source][graffle], [image][gitlab-map]).
-1. When creating a new document and it has more than one word in its name,
-   make sure to use underscores instead of spaces or dashes (`-`). For example,
-   a proper naming would be `import_projects_from_github.md`. The same rule
-   applies to images.
-1. There are four main directories, `user`, `administration`, `api` and `development`.
-1. The `doc/user/` directory has five main subdirectories: `project/`, `group/`,
-   `profile/`, `dashboard/` and `admin_area/`.
-   1. `doc/user/project/` should contain all project related documentation.
-   1. `doc/user/group/` should contain all group related documentation.
-   1. `doc/user/profile/` should contain all profile related documentation.
-      Every page you would navigate under `/profile` should have its own document,
-      i.e. `account.md`, `applications.md`, `emails.md`, etc.
-   1. `doc/user/dashboard/` should contain all dashboard related documentation.
-   1. `doc/user/admin_area/` should contain all admin related documentation
-      describing what can be achieved by accessing GitLab's admin interface
-      (_not to be confused with `doc/administration` where server access is
-      required_).
-      1. Every category under `/admin/application_settings` should have its
-         own document located at `doc/user/admin_area/settings/`. For example,
-         the **Visibility and Access Controls** category should have a document
-         located at `doc/user/admin_area/settings/visibility_and_access_controls.md`.
-1. The `doc/topics/` directory holds topic-related technical content. Create
-   `doc/topics/topic-name/subtopic-name/index.md` when subtopics become necessary.
-   General user- and admin- related documentation, should be placed accordingly.

-### Linking to inline docs
-
-Sometimes it's needed to link to the built-in documentation that GitLab provides
-under `/help`. This is normally done in files inside the `app/views/` directory
-with the help of the `help_page_path` helper method.
-
-In its simplest form, the HAML code to generate a link to the `/help` page is:
-
-```haml
-= link_to 'Help page', help_page_path('user/permissions')
-```
-
-The `help_page_path` contains the path to the document you want to link to with
-the following conventions:
-
-- it is relative to the `doc/` directory in the GitLab repository
-- the `.md` extension must be omitted
-- it must not end with a slash (`/`)
-
-Below are some special cases where should be used depending on the context.
-You can combine one or more of the following:
-
-1. **Linking to an anchor link.** Use `anchor` as part of the `help_page_path`
-   method:
-
-    ```haml
-    = link_to 'Help page', help_page_path('user/permissions', anchor: 'anchor-link')
-    ```
-
-1. **Opening links in a new tab.** This should be the default behavior:
-
-    ```haml
-    = link_to 'Help page', help_page_path('user/permissions'), target: '_blank'
-    ```
-
-1. **Linking to a circle icon.** Usually used in settings where a long
-   description cannot be used, like near checkboxes. You can basically use
-   any font awesome icon, but prefer the `question-circle`:
-
-    ```haml
-    = link_to icon('question-circle'), help_page_path('user/permissions')
-    ```
-
-1. **Using a button link.** Useful in places where text would be out of context
-   with the rest of the page layout:
-
-    ```haml
-    = link_to 'Help page', help_page_path('user/permissions'),  class: 'btn btn-info'
-    ```
-
-1. **Using links inline of some text.**
-
-    ```haml
-    Description to #{link_to 'Help page', help_page_path('user/permissions')}.
-    ```
-
-1. **Adding a period at the end of the sentence.** Useful when you don't want
-   the period to be part of the link:
-
-    ```haml
-    = succeed '.' do
-      Learn more in the
-      = link_to 'Help page', help_page_path('user/permissions')
-    ```
+- 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`](writing_documentation.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)`,

-- **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:
-
-    ```
-    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).

-## Changing document location
-
-Changing a document's location is not to be taken lightly. Remember that the
-documentation is available to all installations under `help/` and not only to
-GitLab.com or http://docs.gitlab.com. Make sure this is discussed with the
-Documentation team beforehand.
-
-If you indeed need to change a document's location, do NOT remove the old
-document, but rather replace all of its contents with a new line:
-
-```
-This document was moved to [another location](path/to/new_doc.md).
-```
+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:
 
-where `path/to/new_doc.md` is the relative path to the root directory `doc/`.
+  ```
+  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.
 
-For example, if you were to move `doc/workflow/lfs/lfs_administration.md` to
-`doc/administration/lfs.md`, then the steps would be:
+### Installation guide
 
-1. Copy `doc/workflow/lfs/lfs_administration.md` to `doc/administration/lfs.md`

+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).
 
-    ```
-    This document was moved to [another location](../../administration/lfs.md).
-    ```
-
-1. Find and replace any occurrences of the old location with the new one.
-   A quick way to find them is to use `git grep`. First go to the root directory
-   where you cloned the `gitlab-ce` repository and then do:
-
-    ```
-    git grep -n "workflow/lfs/lfs_administration"
-    git grep -n "lfs/lfs_administration"
-    ```
-
-NOTE: **Note:**
-If the document being moved has any Disqus comments on it, there are extra steps
-to follow documented just [below](#redirections-for-pages-with-disqus-comments).
-
-Things to note:
-
-- Since we also use inline documentation, except for the documentation itself,
-  the document might also be referenced in the views of GitLab (`app/`) which will
-  render when visiting `/help`, and sometimes in the testing suite (`spec/`).
-- The above `git grep` command will search recursively in the directory you run
-  it in for `workflow/lfs/lfs_administration` and `lfs/lfs_administration`
-  and will print the file and the line where this file is mentioned.
-  You may ask why the two greps. Since we use relative paths to link to
-  documentation, sometimes it might be useful to search a path deeper.
-- The `*.md` extension is not used when a document is linked to GitLab's
-  built-in help page, that's why we omit it in `git grep`.
-- Use the checklist on the documentation MR description template.
-
-### Redirections for pages with Disqus comments
-
-If the documentation page being relocated already has any Disqus comments,
-we need to preserve the Disqus thread.
-
-Disqus uses an identifier per page, and for docs.gitlab.com, the page identifier
-is configured to be the page URL. Therefore, when we change the document location,
-we need to preserve the old URL as the same Disqus identifier.
-
-To do that, add to the frontmatter the variable `redirect_from`,
-using the old URL as value. For example, let's say I moved the document
-available under `https://docs.gitlab.com/my-old-location/README.html` to a new location,
-`https://docs.gitlab.com/my-new-location/index.html`.
-
-Into the **new document** frontmatter add the following:
-
-```yaml
----
-redirect_from: 'https://docs.gitlab.com/my-old-location/README.html'
----
-```
-
-Note: it is necessary to include the file name in the `redirect_from` URL,
-even if it's `index.html` or `README.html`.

+## Documentation directory structure
+
+The documentation is structured based on the GitLab UI structure itself,
+separated by [`user`](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/user),
+[`administrator`](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/administration), and [`contributor`](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/development). 
+
+In order to have a [solid site structure](https://searchengineland.com/seo-benefits-developing-solid-site-structure-277456) for our documentation,
+all docs should be linked. Every new document should be cross-linked to its related documentation, and linked from its topic-related index, when existent.
+
+The directories `/workflow/`, `/gitlab-basics/`, `/university/`, and `/articles/` have
+been deprecated and the majority their docs have been moved to their correct location
+in small iterations. Please don't create new docs in these folders.
+
+### Location and naming documents
+
+The documentation hierarchy can be vastly improved by providing a better layout
+and organization of directories.
+
+Having a structured document layout, we will be able to have meaningful URLs
+like `docs.gitlab.com/user/project/merge_requests/index.html`. With this pattern,
+you can immediately tell that you are navigating a user related documentation
+and is about the project and its merge requests.
+
+Do not create summaries of similar types of content (e.g. an index of all articles, videos, etc.),
+rather organize content by its subject (e.g. everything related to CI goes together)
+and cross-link between any related content.
+
+The table below shows what kind of documentation goes where.
+
+| Directory | What belongs here |
+| --------- | -------------- |
+| `doc/user/` | User related documentation. Anything that can be done within the GitLab UI goes here including `/admin`. |
+| `doc/administration/`  | Documentation that requires the user to have access to the server where GitLab is installed. The admin settings that can be accessed via GitLab's interface go under `doc/user/admin_area/`. |
+| `doc/api/` | API related documentation. |
+| `doc/development/` | Documentation related to the development of GitLab. Any styleguides should go here. |
+| `doc/legal/` | Legal documents about contributing to GitLab. |
+| `doc/install/`| Probably the most visited directory, since `installation.md` is there. Ideally this should go under `doc/administration/`, but it's best to leave it as-is in order to avoid confusion (still debated though). |
+| `doc/update/` | Same with `doc/install/`. Should be under `administration/`, but this is a well known location, better leave as-is, at least for now. |
+| `doc/topics/` | Indexes per Topic (`doc/topics/topic-name/index.md`): all resources for that topic (user and admin documentation, articles, and third-party docs) |
+
+---
+
+**General rules:**
+
+1. The correct naming and location of a new document, is a combination
+   of the relative URL of the document in question and the GitLab Map design
+   that is used for UX purposes ([source][graffle], [image][gitlab-map]).
+1. When creating a new document and it has more than one word in its name,
+   make sure to use underscores instead of spaces or dashes (`-`). For example,
+   a proper naming would be `import_projects_from_github.md`. The same rule
+   applies to images.
+1. Start a new directory with an `index.md` file.
+1. There are four main directories, `user`, `administration`, `api` and `development`.
+1. The `doc/user/` directory has five main subdirectories: `project/`, `group/`,
+   `profile/`, `dashboard/` and `admin_area/`.
+   1. `doc/user/project/` should contain all project related documentation.
+   1. `doc/user/group/` should contain all group related documentation.
+   1. `doc/user/profile/` should contain all profile related documentation.
+      Every page you would navigate under `/profile` should have its own document,
+      i.e. `account.md`, `applications.md`, `emails.md`, etc.
+   1. `doc/user/dashboard/` should contain all dashboard related documentation.
+   1. `doc/user/admin_area/` should contain all admin related documentation
+      describing what can be achieved by accessing GitLab's admin interface
+      (_not to be confused with `doc/administration` where server access is
+      required_).
+      1. Every category under `/admin/application_settings` should have its
+         own document located at `doc/user/admin_area/settings/`. For example,
+         the **Visibility and Access Controls** category should have a document
+         located at `doc/user/admin_area/settings/visibility_and_access_controls.md`.
+1. The `doc/topics/` directory holds topic-related technical content. Create
+   `doc/topics/topic-name/subtopic-name/index.md` when subtopics become necessary.
+   General user- and admin- related documentation, should be placed accordingly.
+
+If you are unsure where a document should live, you can ping `@axil` or `@marcia` in your
+merge request.
+
+### Changing document location
+
+Changing a document's location is not to be taken lightly. Remember that the
+documentation is available to all installations under `help/` and not only to
+GitLab.com or http://docs.gitlab.com. Make sure this is discussed with the
+Documentation team beforehand.
+
+If you indeed need to change a document's location, do NOT remove the old
+document, but rather replace all of its contents with a new line:
+
+```
+This document was moved to [another location](path/to/new_doc.md).
+```
+
+where `path/to/new_doc.md` is the relative path to the root directory `doc/`.
+
+---
+
+For example, if you were to move `doc/workflow/lfs/lfs_administration.md` to
+`doc/administration/lfs.md`, then the steps would be:
+
+1. Copy `doc/workflow/lfs/lfs_administration.md` to `doc/administration/lfs.md`
+1. Replace the contents of `doc/workflow/lfs/lfs_administration.md` with:
+
+    ```
+    This document was moved to [another location](../../administration/lfs.md).
+    ```
+
+1. Find and replace any occurrences of the old location with the new one.
+   A quick way to find them is to use `git grep`. First go to the root directory
+   where you cloned the `gitlab-ce` repository and then do:
 
-### Testing
+    ```
+    git grep -n "workflow/lfs/lfs_administration"
+    git grep -n "lfs/lfs_administration"
+    ```
+
+NOTE: **Note:**
+If the document being moved has any Disqus comments on it, there are extra steps
+to follow documented just [below](#redirections-for-pages-with-disqus-comments).
+
+Things to note:
+
+- Since we also use inline documentation, except for the documentation itself,
+  the document might also be referenced in the views of GitLab (`app/`) which will
+  render when visiting `/help`, and sometimes in the testing suite (`spec/`).
+- The above `git grep` command will search recursively in the directory you run
+  it in for `workflow/lfs/lfs_administration` and `lfs/lfs_administration`
+  and will print the file and the line where this file is mentioned.
+  You may ask why the two greps. Since we use relative paths to link to
+  documentation, sometimes it might be useful to search a path deeper.
+- The `*.md` extension is not used when a document is linked to GitLab's
+  built-in help page, that's why we omit it in `git grep`.
+- Use the checklist on the documentation MR description template.
+
+### Redirections for pages with Disqus comments
+
+If the documentation page being relocated already has any Disqus comments,
+we need to preserve the Disqus thread.
+
+Disqus uses an identifier per page, and for docs.gitlab.com, the page identifier
+is configured to be the page URL. Therefore, when we change the document location,
+we need to preserve the old URL as the same Disqus identifier.
+
+To do that, add to the frontmatter the variable `redirect_from`,
+using the old URL as value. For example, let's say I moved the document
+available under `https://docs.gitlab.com/my-old-location/README.html` to a new location,
+`https://docs.gitlab.com/my-new-location/index.html`.
+
+Into the **new document** frontmatter add the following:
+
+```yaml
+---
+redirect_from: 'https://docs.gitlab.com/my-old-location/README.html'
+---
+```
+
+Note: it is necessary to include the file name in the `redirect_from` URL,
+even if it's `index.html` or `README.html`.

 - [Specific Runner](../ci/runners/README.md#locking-a-specific-runner-from-being-enabled-for-other-projects)
 
+## GitLab `/help`
+
+Every GitLab instance includes the documentation, which is available from `/help`
+(`http://my-instance.com/help`), e.g., <https://gitlab.com/help>.
+
+When you're building a new feature, you may need to link the documentation
+from GitLab, the application. This is normally done in files inside the
+`app/views/` directory with the help of the `help_page_path` helper method.
+
+In its simplest form, the HAML code to generate a link to the `/help` page is:
+
+```haml
+= link_to 'Help page', help_page_path('user/permissions')
+```
+
+The `help_page_path` contains the path to the document you want to link to with
+the following conventions:
+
+- it is relative to the `doc/` directory in the GitLab repository
+- the `.md` extension must be omitted
+- it must not end with a slash (`/`)
+
+Below are some special cases where should be used depending on the context.
+You can combine one or more of the following:
+
+1. **Linking to an anchor link.** Use `anchor` as part of the `help_page_path`
+   method:
+
+    ```haml
+    = link_to 'Help page', help_page_path('user/permissions', anchor: 'anchor-link')
+    ```
+
+1. **Opening links in a new tab.** This should be the default behavior:
+
+    ```haml
+    = link_to 'Help page', help_page_path('user/permissions'), target: '_blank'
+    ```
+
+1. **Linking to a circle icon.** Usually used in settings where a long
+   description cannot be used, like near checkboxes. You can basically use
+   any font awesome icon, but prefer the `question-circle`:
+
+    ```haml
+    = link_to icon('question-circle'), help_page_path('user/permissions')
+    ```
+
+1. **Using a button link.** Useful in places where text would be out of context
+   with the rest of the page layout:
+
+    ```haml
+    = link_to 'Help page', help_page_path('user/permissions'),  class: 'btn btn-info'
+    ```
+
+1. **Using links inline of some text.**
+
+    ```haml
+    Description to #{link_to 'Help page', help_page_path('user/permissions')}.
+    ```
+
+1. **Adding a period at the end of the sentence.** Useful when you don't want
+   the period to be part of the link:
+
+    ```haml
+    = succeed '.' do
+      Learn more in the
