+## Troubleshooting
+
+If outputs differ between runtimes:
+1. Check `tests/output/` for the full outputs from each runtime
+2. Use a diff tool to compare the files
+3. Common issues:
+   - Number formatting differences (should be fixed by locale settings)

+The current implementation prints basic skeleton data. Future expansions will include:
+- Full bone and slot hierarchies
+- All attachment types
+- Animation timelines
+- Constraint data
+- Physics settings
+- Complete runtime state after animation
