GitHub developers can now keep their README.md files current with minimal effort. A recently shared guide on DEV Community outlines how to automatically update the 'Last updated' date in a README file every time code is pushed to a repository using GitHub Actions. This automation is necessary because GitHub does not inherently modify file contents on push.

The setup involves adding a placeholder in the README, creating a GitHub Actions workflow, and enabling the necessary permissions. Once configured, every push to the repository triggers an action that updates the date, commits the change, and pushes it back to the repository. This eliminates the need for manual updates, ensuring that the README always reflects the most recent activity.

By leveraging GitHub Actions, developers can maintain accurate documentation with zero manual effort after the initial setup, streamlining their workflow and keeping their projects up-to-date.
