 This component serves allowed list of keyfob UID hashes from MongoDB and
 pushes open door commands to door controllers.
-We run three instances `replica{1..3}.doorboy.infra.k-space.ee` for high availability.
-To connect from door controllers use round robin record `doorboy.infra.k-space.ee`

 # Testing endpoints
 
 For manually testing something like this might help:
 
 ```
-source .env
-curl -f http://doorboy.infra.k-space.ee:5000/allowed -H "KEY: $DOORBOY_SECRET" | md5sum
+curl -f http://127.0.0.1:5000/allowed -H "KEY: 0123456789"
