 - `PAGE_SIZE` - number of rows to return from a request which returns a list of items
 - `MIRRORS_LIST_URL`: the URL to fetch list of mirrors from.
 - `EXCLUDED_MIRRORS`: hostname of mirror URLs to exclude seperated by commas.
 
 ### REST API
+
 - `JWT_SECRET`
 - `MESSAGE_VALIDITY_DURATION`: how long should the authentication message be considered as valid from when it was signed
 - `TOKEN_EXPIRY_DURATION`: how long access tokens should live
 
 ### scheduler
+
 - `SCHEDULER_SLEEP_DURATION`: how long the scheduler should sleep after creating tests for idle workers
 - `IDLE_WORKER_DURATION`: mark a worker as idle if it hasn't been seen within duration
 - `EXPIRE_TEST_DURATION`: expire tests whose results are still pending after duration
