 GQL uses the python `logging`_ module.
 
 In order to debug a problem, you can enable logging to see the messages exchanged between the client and the server.
-To do that, set the loglevel at **INFO** at the beginning of your code:

 Disabling logs
 --------------
 
-By default, the logs for the transports are quite verbose.
-
-On the **INFO** level, all the messages between the frontend and the backend are logged which can
-be difficult to read especially when it fetches the schema from the transport.
+On the **DEBUG** log level, the logs for the transports are quite verbose.
 
 It is possible to disable the logs only for a specific gql transport by setting a higher
 log level for this transport (**WARNING** for example) so that the other logs of your program are not affected.
