+# Jupyter Notebook Guide
+
+Notebooks are JSON files. Cells are in `nb['cells']`, each has `source` (list of strings) and `cell_type` ('code', 'markdown', or 'raw').
+
+## Modifying Notebooks
+```python
+import json
+with open('notebook.ipynb') as f:
+    nb = json.load(f)
+# Modify nb['cells'][i]['source'], then:
+with open('notebook.ipynb', 'w') as f:
+    json.dump(nb, f, indent=1)
+```
+
+## Executing & Converting
+```bash
+jupyter nbconvert --to notebook --execute --inplace notebook.ipynb  # Execute in place
+jupyter nbconvert --to html notebook.ipynb      # Convert to HTML
+jupyter nbconvert --to script notebook.ipynb    # Convert to Python
+jupyter nbconvert --to markdown notebook.ipynb  # Convert to Markdown
+```
+
+## Finding Code
+```bash
+grep -n "search_term" notebook.ipynb
+```
+
+## Cell Structure
+```python
+# Code cell
+{"cell_type": "code", "execution_count": None, "metadata": {}, "outputs": [], "source": ["code\n"]}
+# Markdown cell
+{"cell_type": "markdown", "metadata": {}, "source": ["# Title\n"]}
+```
+
+## Clear Outputs
+```python
+for cell in nb['cells']:
+    if cell['cell_type'] == 'code':
+        cell['outputs'] = []
+        cell['execution_count'] = None
+```
