Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitLab with WP-CLI:
wp plugin install https://gitlab.com/amirhoseinh73/wc-progress-discount/-/archive/main/wc-progress-discount-main.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
