+## Jupyter Book Conversion Guidelines
+
+When converting LaTeX content to Jupyter Book format:
+
+1. **Content Fidelity**: Keep the Jupyter Book content as close as possible to the LaTeX content. The primary goal is preserving the original text, code examples, and educational material.
+
+2. **Acceptable Changes**:
+   - Convert LaTeX syntax to Markdown (equations, formatting, etc.)
+   - Adjust image paths and convert PDF figures to PNG format
+   - Use Markdown-specific features for better web readability
+   - Convert LaTeX cross-references to Markdown links
+   
+3. **Do NOT**:
+   - Abbreviate or summarize content
+   - Remove code examples or explanations
+   - Change the pedagogical flow or structure
+   - Add new content not present in the original LaTeX
+
+4. **Figure Conversion**: Convert all PDF figures to PNG at 300 DPI for web compatibility while maintaining visual quality.
