+Root Descriptor
+~~~~~~~~~~~~~~~
+
+Root descriptors provide a mechanism for binding individual resources to shader stages in the Direct3D 12 
+rendering pipeline. They allow applications to specify how shader stages access specific GPU resources.

+Version 1.1 of Root Descriptors has introduced some flags that can hint the drivers into

+Version 1.0 Root Descriptor
+'''''''''''''''''''''''''''
+The Version 1.0 RootDescriptor_V1_0 provides basic resource binding:
+
+#. **ShaderRegister**: The shader register where the descriptor is bound.
+#. **RegisterSpace**: The register space used for the binding.
+
+Version 1.1 Root Descriptor
+'''''''''''''''''''''''''''
+The Version 1.1 RootDescriptor_V1_1 extends the base structure with the following additional fields:
+
+#. **Flags**: Provides additional metadata about the descriptor's usage pattern.
