+## Purpose
+
+The Matrix Multiplication sample performs basic matrix multiplication. Three version are provided that use different features of DPC++.
+
+## Key Implementation details
+
+The basic DPC++ implementation explained in the code includes device selector, buffer, accessor, kernel, and command groups.
