+## About EEVEE Render
+
+Bioxel Nodes is designed for Cycles Render. However, it does support eevee render partially. "Solid Shader" node and "Volume Shader" node have a toggle called "EEVEE Render". If you want to render Bioxel Component in real-time, turn it on.
+
+Also, there are some limitations:
+
+1. Only one cutter supported.
+2. You cannot use "Color Ramp" over 2 colors.
+3. EEVEE Render result is not that great as Cycles does.
+
+> "Volume Shader" node is not work properly in EEVEE Next since 4.2. It is because EEVEE Next is not support attributes from instances of volume shader by now. But the Blender 4.2 docs still say attributes reading is ok, so I suppose this feature will eventually be implemented.
