+## Important Notice
+
+**⚠️ This is a Beta/Initial Release (v1.0.x)**
+
+AlphaForge is currently in early development. While fully functional, you may encounter bugs or rough edges.
+
+### Known Issues
+- **Shaft Diameter Accuracy:** The hole diameter for the shaft may be slightly tight or loose depending on your printer's calibration. We are aware that the tolerance calculation needs adjustment.
+- **Workaround:** For now, you can slightly adjust the "Shaft Diameter" slider in the "Shaft Fit" section to compensate for your printer's tolerance (e.g., add 0.2mm - 0.4mm).
