 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. ``idf.py menuconfig`` is not supported by automatic hints on resolving 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 menuconfig, gdb and openocd targets are 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.
