+- ✅ `viewcode` - Source code links
+- ✅ `intersphinx` - Cross-references to Python docs
+- ✅ `sphinx_click` - CLI documentation
+- ✅ `myst_parser` - Markdown support
+
+### Autodoc Configuration
+
+```python
+autodoc_default_options = {
+    "members": True,              # Include all members
+    "member-order": "bysource",   # Maintain source order
+    "special-members": "__init__", # Include constructors
+    "undoc-members": True,        # Include undocumented
+    "show-inheritance": True,     # Show base classes
+}
+```
+
+## GitHub Pages Deployment
+
+### Automatic Deployment
+
+Documentation automatically rebuilds and deploys when:
+- Code changes are pushed to main/master
+- Changes are made to `src/**`, `docs/**`, workflows, or `pyproject.toml`
+- Manual workflow trigger
+
+### Workflow Features
+
+1. **Build Job**
+   - Checks out repository
+   - Sets up Python 3.10
+   - Installs Hatch
+   - Builds documentation with `hatch run docs:build`
+   - Uploads artifact for Pages deployment
+
+2. **Deploy Job** (main/master only)
+   - Deploys to GitHub Pages
+   - Updates documentation site
+   - Provides deployment URL
+
+### GitHub Pages URL
+
+Documentation available at: https://jango-blockchained.github.io/PyneScript/
