+## Updating CRunDec version
+
+To update to a new version of CRunDec:
+
+1. Replace the CRunDec source files in the `CRunDec3/` directory with the new version, renaming them to `CRunDec.cpp` and `CRunDec.h`
+
+2. Update `setup.py` to reference the correct source files
+
+3. Check if `rundec.i` needs updates for any API changes (e.g., new types, changed function signatures)
+
+4. Regenerate the wrapper and test:
+   ```bash
+   make
+   pip install -e .
+   pytest test/
+   ```
