 # Testing
 
-Your pull request will automatically be built and available under the following folder:
-https://openhab.jfrog.io/ui/native/libs-pullrequest-local/org/openhab/addons/bundles/
-
 It is a good practice to add a URL to your built JAR in this pull request description,
 so it is easier for the community to test your Add-on.
 If your pull request contains a new binding, it will likely take some time

 When creating a pull request, read and follow `.github/PULL_REQUEST_TEMPLATE.md` for the repository's current PR requirements.
 
 - Treat HTML-commented template text as instructions and write visible Markdown that addresses the applicable requirements; do not copy the comment delimiters or leave the PR description hidden inside an HTML comment.
-- The template's guidance about linking to automatically generated pull-request build artifacts is currently outdated; do not add such artifact links.
 - Before creating or updating a pull request, verify that its title and description still match the current diff and scope, especially after follow-up changes.
 - Treat the template as the source of truth for the remaining pull-request requirements rather than duplicating them here.
