+## Manual testing checklist
+
+Sometimes changes are made which could potentially affect any page, e.g. updating the templating library.
+In that case it's necessary to manually check (almost) every page for obvious regressions before deploying the update.
+To facilitate that, here's a list of links to the staging deployment.
+Note that like all documentation, this list may become outdated over time.
+So stay vigilant and update it if you notice something missing.
