 ### Profiles
 
 This option can be used to enable/disable available JavaScript language features by providing profile files. Profile files contain a list of C definitions that configure each individual feature.
-The `path` value for CMake and Python arguments should be a file path to the profile file, or one of `es.next`, `es5.1`, or `minimal`, which are the pre-defined profiles.

 To see how a profile file should be created, or what configuration options are available in C, see the profile [README](https://github.com/jerryscript-project/jerryscript/blob/master/jerry-core/profiles/README.md).
