+## Legal document generator module
+
+This repository includes a simple example module located in `legal_module/` that demonstrates how to generate Traditional Chinese legal filings using the `python-docx` package. The module exposes a `create_filing` function that accepts case information and outputs a formatted Word document.  When `docx2pdf` is available the file can also be exported to PDF.  Generated documents use **2.5 cm margins**, **1.5 line spacing**, and include an optional **附件** section for supporting materials.
+
+Example usage:
+
+```bash
+python3 -m legal_module.example
+```
+
+This requires the optional dependencies **python-docx** and **docx2pdf** for PDF export. Install them with:
+
+```bash
+pip install python-docx docx2pdf
+```
