 ## Allowlist
-The allowlist determines to which queryservices federated queries can be made.
-This list should contain at least the services that are allowed on the wikidata
-queryservice and any Wikibase Cloud hosted Wikibases
 
-To update the list to include new Wikibase Cloud wikis one can run the following:
-```lang=bash
-kubectl exec -it deployment/api-app-backend -- php artisan tinker --execute '\App\Wiki::all()->pluck("domain")->each(function ($i, $k) { echo "https://".$i."/query/sparql".PHP_EOL; })' > allowlist.txt
-cat allowlist-static.txt >> allowlist.txt
+The allowlist determines which query services can be used for federated queries. This list is provided at runtime by mounting a newline-delimited text file of endpoints to `/wdqs/allowlist.txt`. It should include all instances hosted by Wikibase Cloud.
+
+Example for `allowlist.txt`:
