====== Cupboard – Instructions for Modules ======
Instructions for each module are available by left-clicking the module in the Cupboard. A window with the instructions for that module appears on the screen.

The instructions for each module describe:
  - what the algorithm does to the image
  - what parameters are available to be set for the module
  - what the parameter values will do
  - what type of input and output images the module will take and produce

You can also open the same instructions from a module on the Desktop: every argument dialog has a **Help** button (question-mark icon). See [[basic_level:readimage_and_show|ReadImage and Show]].
