+
+\# Windows Development Guide
+
+
+
+This guide helps Windows developers contribute to the Kubernetes Python Client.
+
+
+
+---
+
+
+
+\## 🧰 Prerequisites
+
+
+
+\- Python 3.8+ (Recommended: Python 3.11+)
+
+\- Git for Windows
+
+\- PowerShell or Command Prompt
+
+
+
+---
+
+
+
+\## ⚙️ Setup for Windows Development
+
+
+
+\### 1. Clone and setup the repository:
+
+
+
+```bash
+
+git clone https://github.com/your-username/kubernetes-client-python.git
+
+cd kubernetes-client-python
+
+python setup-windows-dev.py
+
+```
+
+
+
+\### 2. Install in development mode:
+
+
+
+```bash
+
+pip install -e .
+
+pip install -r test-requirements.txt
+
+```
+
+
+
+\### 3. Run tests:
+
+
+
+```bash
+
+python -m pytest kubernetes/base/watch/watch\_test.py -v
+
+```
+
+
+
+---
+
+
+
+\## 🐞 Known Windows Issues and Solutions
+
+
+
+\### 🔗 Symlink Directories
+
+\- \*\*Problem:\*\* `kubernetes/config` and `kubernetes/watch` are symlinks that don't work on Windows.
+
+\- \*\*Solution:\*\* Run `python setup-windows-dev.py` to create proper directory copies.
+
+
+
+\### ❌ Missing Imports
+
+\- \*\*Problem:\*\* Some test files were missing `import json`.
+
+\- \*\*Solution:\*\* Fixed in the codebase.
+
+
+
+\### 🔒 Permission Errors
+
+\- \*\*Problem:\*\* Temporary file creation fails with `PermissionError`.
+
+\- \*\*Solution:\*\* Tests now handle Windows permissions gracefully.
+
+
+
+---
+
+
+
+\## 🤝 Contributing
+
+
+
+When contributing from Windows:
+
+
+
+1\. Always run the setup script first.
+
+2\. Test your changes locally.
+
+3\. Include Windows-specific considerations in your PRs.
