+- There's no need to wrap the titles, unless there's a special char in it. For example,

 ##### URLs
 
-- As convention, always wrap URLs in single quotes `'url'`.
-- Always use relative paths against the home of CE and EE. Examples:
-  - For `https://docs.gitlab.com/ee/README.html`, the relative URL is `README.html`.
-  - For `https://docs.gitlab.com/ee/user/analytics/value_stream_analytics.md`, the relative

-- For `README.html` files, add the complete path `path/to/README.html`.
-- For `index.html` files, use the clean (canonical) URL: `path/to/`.
-- For EE-only docs, use the same relative path, but add the attribute `ee_only: true` below

 ### Layout file (logic)
 
@@ -318,74 +271,15 @@ The [layout](https://gitlab.com/gitlab-org/gitlab-docs/blob/master/layouts/globa
 is fed by the [data file](#data-file), builds the global nav, and is rendered by the
 [default](https://gitlab.com/gitlab-org/gitlab-docs/blob/master/layouts/default.html) layout.
 
-There are three main considerations on the logic built for the nav:
-
-- [Path](#path): first-level directories underneath `docs.gitlab.com/`:
-  - `https://docs.gitlab.com/ce/`
-  - `https://docs.gitlab.com/ee/`
-  - `https://docs.gitlab.com/omnibus/`
-  - `https://docs.gitlab.com/runner/`
-  - `https://docs.gitlab.com/*`
-- [EE-only](#ee-only-docs): documentation only available in `/ee/`, not on `/ce/`, e.g.:
-  - `https://docs.gitlab.com/ee/user/group/epics/`
-  - `https://docs.gitlab.com/ee/user/application_security/security_dashboard/index.html`
-- [Default URL](#default-url): between CE and EE docs, the default is `ee`, therefore, all docs
-  should link to `/ee/` unless if on `/ce/` linking internally to `ce`.
-
-#### Path
-
-To use relative paths in the data file, we defined the variable `dir`
-from the root's first-child directory, which defines the path to build
-all the nav links to other pages:
-
-```html
-<% dir = @item.identifier.to_s[%r{(?<=/)[^/]+}] %>
-```
-
-For instance, for `https://docs.gitlab.com/ee/user/index.html`,
-`dir` == `ee`, and for `https://docs.gitlab.com/omnibus/README.html`,
-`dir` == `omnibus`.
-
-#### Default URL
-
-The default and canonical URL for GitLab documentation is
-`https://docs.gitlab.com/ee/`, thus, all links
-in the docs site should link to `/ee/` except when linking
-among `/ce/` docs themselves.
-
-Therefore, if the user is looking at `/ee/`, `/omnibus/`,
-`/runner/`, or any other highest-level dir, the nav should
-point to `/ee/` docs.
-
-On the other hand, if the user is looking at `/ce/` docs,
-all the links in the CE nav should link internally to `/ce/`
-files.
-
-```html
-<% if dir != 'ce' %>
-  <a href="/ee/<%= sec[:section_url] %>">...</a>
-  <% else %>
-    <a href="/<%= dir %>/<%= sec[:section_url] %>">...</a>
-  <% end %>
-  ...
-<% end %>
-```
-
-This also allows the nav to be displayed on other
-highest-level directories (`/omnibus/`, `/runner/`, etc),
-linking them back to `/ee/`.
-
-The same logic is applied to all sections (`sec[:section_url]`),
-categories (`cat[:category_url]`), and docs (`doc[:doc_url]`) URLs.
-
-#### `ee-only` docs
-
-Docs for features present only in GitLab EE are tagged
-in the data file by `ee-only` and an icon is displayed on the nav
-link indicating that the `ee-only` feature is not available in CE.
+The global nav contains links from all [four upstream projects](index.md#architecture).
+The [global nav URL](#urls) has a different prefix depending on the documentation file you change.
 
-The `ee-only` attribute is available for `categories` (`<% if cat[:ee_only] %>`)
-and `docs` (`<% if doc[:ee_only] %>`), but not for `sections`.
+| Repository                                                     | Link prefix | Final URL |

-# Monthly release process
+This file was moved to [another location](https://about.gitlab.com/handbook/engineering/ux/technical-writing/workflow/#monthly-documentation-releases).
 
-When a new GitLab version is released on the 22nd, we need to release the published documentation
-for the new version.
-
-This should be done as soon as possible after the GitLab version is announced, so that:
-
-- The published documentation includes the three most recent minor releases of the current major
-  version, and the most recent minor releases of the last two major versions. For example 13.9,
-  13.8, 13.7, 12.10, and 11.11.
-- Documentation updates after the 22nd are for the next release. The versions drop down
-  should have the current milestone with `-pre` appended to it, for example `13.10-pre`.
-
-Each documentation release:
-
-- Has a dedicated branch, named in the format `XX.yy`.
-- Has a Docker image that contains a build of that branch.
-
-For example:
-
-- For [GitLab 13.9](https://docs.gitlab.com/13.9/index.html), the
-  [stable branch](https://gitlab.com/gitlab-org/gitlab-docs/-/tree/13.9) and Docker image:
-  [`registry.gitlab.com/gitlab-org/gitlab-docs:13.9`](https://gitlab.com/gitlab-org/gitlab-docs/container_registry/631635).
-- For [GitLab 13.8](https://docs.gitlab.com/13.8/index.html), the
-  [stable branch](https://gitlab.com/gitlab-org/gitlab-docs/-/tree/13.8) and Docker image:
-  [`registry.gitlab.com/gitlab-org/gitlab-docs:13.8`](https://gitlab.com/gitlab-org/gitlab-docs/container_registry/631635).
-
-To set up a documentation release, follow these steps:
-
-1. [Add the charts version](#add-chart-version), so that the documentation is built using the
-   [version of the charts project that maps to](https://docs.gitlab.com/charts/installation/version_mappings.html)
-   the GitLab release. This step may have been completed already.
-1. [Create a stable branch and Docker image](#create-stable-branch-and-docker-image-for-release) for
-   the new version.
-1. [Create a release merge request](#create-release-merge-request) for the new version, which
-   updates the version dropdown menu for the current documentation and adds the release to the
-   Docker configuration. For example, the
-   [release merge request for 13.9](https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests/1555).
-1. [Update the three online versions](#update-dropdown-for-online-versions), so that they display the new release on their
-   version dropdown menus. For example:
-   - The merge request to [update the 13.9 version dropdown menu for the 13.9 release](https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests/1556).
-   - The merge request to [update the 13.8 version dropdown menu for the 13.9 release](https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests/1557).
-   - The merge request to [update the 13.7 version dropdown menu for the 13.9 release](https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests/1558).
-1. [Merge the release merge request and run the necessary Docker image builds](#merge-release-merge-request-and-run-docker-image-builds).
-
-## Add chart version
-
-To add a new charts version for the release:
-
-1. Make sure you're in the root path of the `gitlab-docs` repository.
-1. Open `content/_data/chart_versions.yaml` and add the new stable branch version using the
-   [version mapping](https://docs.gitlab.com/charts/installation/version_mappings.html). Only the
-   `major.minor` version is needed.
-1. Create a new merge request and merge it.
-
-NOTE:
-If you have time, add anticipated future mappings to `content/_data/chart_versions.yaml`. This saves
-a step for the next GitLab release.
-
-## Create stable branch and Docker image for release
-
-To create a stable branch and Docker image for the release:
-
-1. Make sure you're in the root path of the `gitlab-docs` repository.
-1. Run the Rake task to create the single version. For example, to create the 13.9 release branch
-   and perform others tasks:
-
-   ```shell
-   ./bin/rake "release:single[13.9]"
-   ```
-
-    A branch for the release is created, a new `Dockerfile.13.9` is created, and `.gitlab-ci.yml`
-    has branches variables updated into a new branch. These files are automatically committed.
-
-1. Push the newly created branch, but **don't create a merge request**. After you push, the
-   `image:docs-single` job creates a new Docker image tagged with the name of the branch you created
-   earlier. You can see the Docker image in the `registry` environment at
-   <https://gitlab.com/gitlab-org/gitlab-docs/-/environments/folders/registry>.
-
-For example, see [the 13.9 release pipeline](https://gitlab.com/gitlab-org/gitlab-docs/-/pipelines/260288747).
-
-Optionally, you can test locally by:
-
-1. Building the image and running it. For example, for GitLab 13.9 documentation:
-
-   ```shell
-   docker build -t docs:13.9 -f Dockerfile.13.9 .
-   docker run -it --rm -p 4000:4000 docs:13.9
-   ```
-
-1. Visiting <http://localhost:4000/13.9/> to see if everything works correctly.
-
-## Create release merge request
-
-NOTE:
-An [epic is open](https://gitlab.com/groups/gitlab-org/-/epics/4361) to automate this step.
-
-To create the release merge request for the release:
-
-1. Make sure you're in the root path of the `gitlab-docs` repository.
-1. Create a branch `release-X-Y`. For example:
-
-   ```shell
-   git checkout master
-   git checkout -b release-13-9
-   ```
-
-1. Edit `content/_data/versions.yaml` and update the lists of versions to reflect the new release:
-
-   - Add the latest version to the `online:` section.
-   - Move the oldest version in `online:` to the `offline:` section. There should now be three
-     versions in `online:`.
-
-1. Update these Dockerfiles:
-
-   - `dockerfiles/Dockerfile.archives`: Add the latest version to the top of the list.
-   - `Dockerfile.master`: Remove the oldest version, and add the newest version to the
-     top of the list.
-
-1. Commit and push to create the merge request. For example:
-
-   ```shell
-   git add content/ Dockerfile.master dockerfiles/Dockerfile.archives
-   git commit -m "Release 13.9"
-   git push origin release-13-9
-   ```
-
-Do not merge the release merge request yet.
-
-## Update dropdown for online versions
-
-To update`content/_data/versions.yaml` for all online versions (stable branches `X.Y` of the
-`gitlab-docs` project):
-
-1. Run the Rake task that creates all of the necessary merge requests to update the dropdowns. For
-   example, for the 13.9 release:
-
-   ```shell
-   git checkout release-13-9
-   ./bin/rake release:dropdowns
-   ```
-
-   These merge requests are set to automatically merge.
-
-1. [Visit the merge requests page](https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests?label_name%5B%5D=release)
-   to check that their pipelines pass. After all MRs are merged, proceed to the following and final
-   step.
-
-## Merge release merge request and run Docker image builds
-
-The merge requests for the dropdowns should now all be merged into their respective stable branches.
-Each merge triggers a new pipeline for each stable branch. Wait for the stable branch pipelines to
-complete, then:
-
-1. Check the [pipelines page](https://gitlab.com/gitlab-org/gitlab-docs/pipelines)
-   and make sure all stable branches have green pipelines.
-1. After all the pipelines succeed, merge the [release merge request](#create-release-merge-request).
-1. Finally, run the
-   [`Build docker images weekly` pipeline](https://gitlab.com/gitlab-org/gitlab-docs/pipeline_schedules)
-   that builds the `:latest` and `:archives` Docker images.
-
-As the last step in the scheduled pipeline, the documentation site deploys with all new versions.
