+# Copy Kernel
+This folder contains basic setup code designed to provide a platform for novice 
+CK_Tile kernel developers to test basic functionality with minimal additional 
+code compared to the functional code. Sample functional code for a simple
+tile distribution for DRAM window and LDS window are provided and data is moved
+from DRAM to registers, registers to LDS, LDS to registers and finally data
+is moved to output DRAM window for a simple copy operation.
+
+## 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>
+# Make the copy kernel executable
+make test_copy -j
+```
+This will result in an executable `build/bin/test_copy_kernel`
+
+## example
+```
+args:
+          -m        input matrix rows. (default 64)
+          -n        input matrix cols. (default 8)
+          -id       warp to use for computation. (default 0)
+          -v        validation flag to check device results. (default 1)
+          -prec     datatype precision to use. (default fp16)
+          -warmup   no. of warmup iterations. (default 50)
+          -repeat   no. of iterations for kernel execution time. (default 100)
