The `README.md` file is opened using `open('README.md', 'r')` but is never explicitly closed. This can lead to resource leaks, especially in long-running processes or if the script were to be extended to open many files. While Python's garbage collector might eventually close it, it's not guaranteed and is considered bad practice.
