+- The contributor can add various types of tests (like unit tests or end-to-end tests), which, in their opinion, will be necessary and sufficient for testing new or changed functionality
 - Tests should cover a successful execution, as well as some edge cases and possible errors
 - As already mentioned, pull requests without tests will be considered more carefully by maintainers. If you are sure that in this situation the tests are not needed or cannot be implemented with a commensurate effort - please add this clarification message to your pull request
 
 **Once you've filed the pull request:**
 
 - CI will start automatically with some checks. Wait until the end of the execution and make sure that all checks passed successfully. If some checks fail, you can open them one by one, try to find the reason for failing and make changes to your code to resolve the problem
 - Maintainers will review your pull request

 - If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action and updating the major tag
 > Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:
