 The super-linter allows you to pass the following `ENV` variables to be able to trigger different functionality.
 
 _Note:_ All the `VALIDATE_[LANGUAGE]` variables behave in a very specific way:
+
 - If none of them are passed, then they all default to true.
 - If any one of the variables are set to true, we default to leaving any unset variable to false (only validate those languages).
 - If any one of the variables are set to false, we default to leaving any unset variable to true (only exclude those languages).

+## Filter linted files

+If you need to lint only a folder or exclude some files from linting, you can use optional environment parameters `FILTER_REGEX_INCLUDE` and `FILTER_REGEX_EXCLUDE`
+
+Examples :
+
+- Lint only src folder: `INCLUDED_FILES_REGEX=.*src/.*`
+- Do not lint files inside test folder: `EXCLUDED_FILES_REGEX=.*test/.*`
+- Do not lint javascript files inside test folder: `EXCLUDED_FILES_REGEX=.*test/.*.js`
