 # After calling 'configure', the gem loads all relevant GTFS info into a database.
 # This may take some time (up to a minute) depending on the size of the input data.
 # By default, gtfs-realtime uses an in-memory database, which requires reloading all
 # data from scratch on each launch. If you'd like to use a persistent database instead,
-# set the 'GTFS_DATABASE_PATH' environment variable, and a SQLite DB will be generated.
+# set 'config.database_path' above, and include a scheme/protocol path for the DB type
+# that you would like to use. gtfs-realtime will generate the relevant tables.
