+## Project implementation
+
+This repository contains not only the plan text, but also a small Python project that implements a basic progress tracker for this plan.
+
+### Source files
+
+- `main.py` — CLI entrypoint.
+- `src/fluency_tracker/tracker.py` — parser of markdown checklist and report builder.
+- `src/fluency_tracker/cli.py` — command-line interface.
+- `requirements.txt` / `pyproject.toml` — dependency and project configuration files.
+
+### Run locally
+
+```bash
+python -m pip install -r requirements.txt
+python main.py --plan-file README.md
+```
+
+The command prints current progress and pending items from checklist tasks (`- [ ]` / `- [x]`).
