+# Project Documentation
+
+## Overview
+
+This repository demonstrates a simple Python "Hello, World" project with a flat package layout. It is designed to help new employees quickly understand the structure, usage, and workflows of the project.
+
+### Key Files and Structure
+- `helloworld.py`: Entry-point script to run the program.
+- `helloworld/`: Package directory containing:
+  - `main.py`: Main implementation of the hello world logic and CLI.
+  - `__init__.py`: Loads the package version from `VERSION.txt`.
+  - `VERSION.txt`: Stores the package version.
+- `README.md`: Basic usage instructions and installation guide.
+- `.github/workflows/documentation_updater.yml`: GitHub Actions workflow to automatically update documentation when pull requests are merged.
+
+## How It Works
+- Running `helloworld.py` or installing the package and running `helloworld_in_python` prints "Hello, world".
+- The version is managed in `helloworld/VERSION.txt` and loaded at runtime.
+- The CLI supports `--version` and `--help` flags.
+
+## Development Workflow
+1. **Clone the repository** and install dependencies (if any).
+2. **Make changes** to code or documentation as needed.
+3. **Commit and push** changes to a feature branch.
+4. **Create a pull request** to merge changes into `main`.
+5. **Merge the pull request** after review.
+6. **Documentation Agent Workflow**: When a PR is merged into `main`, the GitHub Actions workflow `.github/workflows/documentation_updater.yml` automatically updates `documentation.md` with details of the merged PR.
+
+## Automated Documentation Workflow
+- The workflow triggers on closed pull requests targeting `main`.
+- If the PR was merged, it checks out the repo, sets up a bot user, and appends PR details to `documentation.md`.
+- This ensures a running log of changes and contributors for easy onboarding.
+
+## Getting Started
+- See `README.md` for installation and usage.
+- Review `documentation.md` for a history of changes and merged PRs.
+- Explore the code in `helloworld/` for implementation details.
+
+## Contact
+For questions, reach out to the repository owner or check the latest entries in `documentation.md` for recent contributors.
