The above two kinds of styles to launch the kernel are supported, see the documentation of :class:`cupyx.jit._interface._JitRawKernel` for details.
-The two first entries are the grid and block sizes. grid( Rawkernel style (128,) or Numba style [128] ) is the size of the grid in blocks. block( (1024,) or [1024] ) is the dimensions of each thread block.
+The two first entries are the grid and block sizes. ``grid`` ( Rawkernel style ``(128,)`` or Numba style ``[128]``) is the size of the grid, i.e., the number of blocks. ``block`` (``(1024,)`` or ``[1024]``) is the dimensions of each thread block.
This technique is used in CUDA Programming.
