+## Deploy artifacts manually
+
+If there are concerns that the webhook is not behaving as it should,
+it's possible to call the "puller" directly by hand. For example,
+given the [Pipeline 13285](https://gitlab.torproject.org/tpo/tpa/status-site/-/pipelines/13285) has [job 38077](https://gitlab.torproject.org/tpo/tpa/status-site/-/jobs/38077), we can tell the
+puller to deploy in debugging mode with this command:
+
+    sudo -u static-gitlab-shim /usr/local/bin/static-gitlab-shim-pull --artifacts-url https://gitlab.torproject.org/tpo/tpa/status-site/-/jobs/38077/artifacts/download --site-url status.torproject.org --debug
+
+The `--artifacts-url` is the `Download` link in the job page.
