 # Documenting product versions
 
-GitLab product documentation pages (not including [Contributor and Development](../../index.md)
-pages in the `/development` directory) can include version information to help
-users be aware of recent improvements or additions.
+The GitLab product documentation includes version-specific information,
+including when features were introduced and when they were updated or removed.
 
-The GitLab Technical Writing team determines which versions of
-documentation to display on this site based on the GitLab
-[Statement of Support](https://about.gitlab.com/support/statement-of-support.html#version-support).
+## View older documentation versions
 
-## View older GitLab documentation versions
+Previous versions of the documentation are available on `docs.gitlab.com`.
+To view a previous version, select the **Versions** button in the top right.
 
-Older versions of GitLab may no longer have documentation available from `docs.gitlab.com`.
-If documentation for your version is no longer available from `docs.gitlab.com`, you can still view a
-tagged and released set of documentation for your installed version:
+To view versions that are not available on `docs.gitlab.com`:
 
-- In the [documentation archives](https://docs.gitlab.com/archives/).
-- At the `/help` URL of your GitLab instance.
-- In the documentation repository based on the respective branch (for example,
-  the [13.2 branch](https://gitlab.com/gitlab-org/gitlab/-/tree/13-2-stable-ee/doc)).
+- View the [documentation archives](https://docs.gitlab.com/archives/).
+- Go to the GitLab repository and select the version-specific branch. For example,
+  the [13.2 branch](https://gitlab.com/gitlab-org/gitlab/-/tree/13-2-stable-ee/doc) has the
+  documentation for GitLab 13.2.
 
-## Where to put version text
+## Documenting version-specific features
 
 When a feature is added or updated, you can include its version information
-either as a **Version history** item or as an inline text reference.
+either as a **Version history** bullet or as an inline text reference.
 
-### Version text in the **Version History**
+You do not need to add version information on the pages in the `/development` directory.
 
-If all content in a section is related, add version text after the header for
-the section. The version information must:
+### Add a **Version history** bullet
 
-- Be surrounded by blank lines.
-- Start with `>`. If there are multiple bullets, each line must start with `> -`.
-- The string must include these words in this order (capitalization doesn't matter):
-  - `introduced`, `enabled`, `deprecated`, `changed`, `moved`, `recommended` (as in the
-    [feature flag documentation](feature_flags.md)), `removed`, or `renamed`

-```
+1. Add `(deprecated)` after the title. Use a warning to explain when it was deprecated,
+   when it will be removed, and the replacement feature.
 
-You can also describe the replacement in surrounding text, if available. If the
-deprecation isn't obvious in existing text, you may want to include a warning:
+   ```markdown
+   ## Title (deprecated) **(ULTIMATE SELF)**
 
-```markdown
-WARNING:
-This feature was [deprecated](link-to-issue) in GitLab 12.3 and replaced by
-[Feature name](link-to-feature-documentation).
-```
+   WARNING:
+   This feature was [deprecated](<link-to-issue>) in GitLab 14.8
+   and is planned for removal in 15.4. Use [feature X](<link-to-issue>) instead.
+   ```
 
-If you add `(DEPRECATED)` to the page's title and the document is linked from the docs
-navigation, either remove the page from the nav or update the nav item to include the
-same text before the feature name:
+   If you're not sure when the feature will be removed or no
+   replacement feature exists, you don't need to add this information.

-### End-of-life for features or products
+   You can add any additional context-specific details that might help users.
 
-When a feature or product enters its end-of-life, indicate its status by
-creating a [warning alert](styleguide/index.md#alert-boxes) directly after its relevant header.
-If possible, link to its deprecation and removal issues.
+1. Open a merge request to add the word `(deprecated)` to the left nav, after the page title.
