 Customized comment message can be configured as `plugin hint` to express suggestions regarding the plugin's intented behavior. + 
 Eg. Configuring `plugin hint` for the `test-keeper` plugin adds comment message to the Pull Request when no test is found. 
 
-To enable customized plugin hint comment messages edit plugin's configuration file (eg. test-keeper.yaml) adding the `plugin_hint` property.
+By default, the custom plugin hint message is loaded from a file `PLUGINNAME_HINT.md` located in `.ike-prow/` directory (if present). The `PLUGINNAME` is a name of the plugin you want to set the custom hint message for, so for example `.ike-prow/test-keeper_hint.md`.
+It is also possible to set other location of the hint file or directly the content of the message by editing plugin's configuration file (eg. test-keeper.yaml) and adding the `plugin_hint` property there:

The location of the file can be set by either a relative path or an absolute URL. If nothing is set then a default message is used.
