 Hints on how to resolve errors
 ==============================
 
-``idf.py`` will try to suggest hints on how to resolve errors. It works with a database of hints stored in :idf_file:`tools/idf_py_actions/hints.yml` and the hints will be printed if a match is found for the given error. The monitor and menuconfig targets are not supported at the moment by automatic hints on resolving errors.

The menuconfig target is not supported at the moment by automatic hints on resolving errors.
 
 The ``--no-hints`` argument of ``idf.py`` can be used to turn the hints off in case they are not desired.
