+#Multiple D GEMM
+
+This folder contains example for Multiple D GEMM using ck_tile tile-programming implementation.
+
+## build
+```
+#in the root of ck_tile
+mkdir build && cd build
+#you can replace < arch> with the appropriate architecture(for example gfx90a or gfx942) or \
+    leave it blank
+sh ../script/cmake-ck-dev.sh  ../ <arch>
+#The basic pipeline method on the gemm calculation
+make tile_example_gemm_multi_d_fp16 -j
+```
+This will result in an executable `build/bin/tile_example_gemm_multi_d_fp16`
+
+## example
+```
