+## Manually delete a review app
+
+If, for some reason, a `stop-review` job did not run or failed to run,
+the review environment will still be on the `static-shim` server. This
+could use up precious disk space, so it's preferable to remove it by
+hand.
+
+The first thing is to find the review slug. If, for example, you have
+a URL like:
+
+    https://review.torproject.org/tpo/tpa/status-site/review-extends-8z647c
+
+The slug will be:
+
+    review-extends-8z647c
+
+Then you need to remove that directory on the `static-gitlab-shim`
+server. Remember there is a `subdir` to squeeze in there. The above
+URL would be deleted with:
+
+    rm -rf /srv/static-gitlab-shim/review.torproject.net/public/tpo/tpa/status-site/review-extends-8z647c/
+
+Then sync the result to the mirrors:
+
+    static-update-component review.torproject.net
