 ## Approach
 
-This takes a naive two pass approach -
-
--   first pass - compare every pixel between the images and check for differences, and display the comparison status.
--   second pass - (if the `highlight` option is enabled)
-    -   compare every pixel in each block (default: `10x10` pixels) and check for differences, and if there is any, highlight the block.
-    -   store the output with the file name specified in the `output` option (default `TARGET_FILE_NAME_diff`).
