+Override the default Renovate sidecar Docker containers image prefix from `docker.io/renovate` to a custom value, so Renovate will pull images from a custom Docker registry.
 
 If this is set to `ghcr.io/renovatebot` the final image for `node` would become `ghcr.io/renovatebot/node` instead of currently used `docker.io/renovate/node`.

+# Self-hosted experimental environment variables
+
+The following environment variables are "experimental" because:
+
+- They are not commonly needed
+- They are typically an effort to work around some other service's or platform's problem
+- They can be removed at any time
+- They are variables for Renovate's internal use to validate they work as intended
+
+Experimental variables which are commonly used and for which there is no external solution in sight can be converted to a official configuration option by the Renovate bot developers.
+
+Use these experimental variables at your own risk.
+We do not follow Semantic Versioning for any experimental variables.
+These variables may be removed or have their behavior changed in **any** version.
+We will try to keep breakage to a minimum, but make no guarantees that a experimental variable will keep working.
+
+## GITLAB_IGNORE_REPO_URL
+
+If set to any value, Renovate will ignore the Project's `http_url_to_repo` value and instead construct the Git URL manually.
+
+## RENOVATE_CACHE_NPM_MINUTES
+
+If set to any integer, Renovate will use this integer instead of the default npm cache time (15 minutes) for the npm datasource.
+
+## RENOVATE_EXPERIMENTAL_NO_MAVEN_POM_CHECK
+
+If set to any value, Renovate will skip its default artifacts filter check in the Maven datasource.
+Skiping the check will speed things up, but may result in versions being returned which don't properly exist on the server.
+
+## RENOVATE_LEGACY_GIT_AUTHOR_EMAIL
+
+An additional `gitAuthor` email to ignore.
+This variable is deprecated: use `ignoredAuthors` instead.
+
+## RENOVATE_PAGINATE_ALL
+
+If set to any value, Renovate will always paginate requests to GitHub fully, instead of stopping after 10 pages.
+
+## RENOVATE_REUSE_PACKAGE_LOCK
+
+If set to "false" (string), Renovate will remove any existing `package-lock.json` before attempting to update it.
+
+## RENOVATE_USER_AGENT
+
+If set to any string, Renovate will use this as the `user-agent` it sends with HTTP requests.
+
+## RENOVATE_X_HARD_EXIT
+
+If set to any value, Renovate will use a "hard" `process.exit()` once all work is done, even if a sub-process is otherwise delaying Node.js from exiting.
+See <https://github.com/renovatebot/renovate/issues/8660> for background on why this was created.
