write_tile usage problem

[yasohasakii]

hi, I'm confused with write_tile API,

tif.write_tiles(arr,tile_width = tilesize,tile_height = tilesize, compression='lzw', write_rgb=True)

I don't know how to write a whole big image with tiles, because so many tile positions but your API have no parameters of location. please tell me if there any documents or examples to use it correctly,thanks.
