 Most contribution (we imagine) would be in the form of API-compatible modules, which need not be directly included.
 
-**This is a draft proposal: currently, onComplete assignment is done through `module.options.onComplete` -- clearly non-ideal.**
-
 To add a module to Image Sequencer, it must have the following method; you can wrap an existing module to add them:
 
-* `module.draw(onComplete)`
+* `module.draw(image)`
 
-The `draw()` method should accept two paramters, `image` and `onComplete`. The `onComplete` parameter will be a function with one parameter, and will be set to the `draw()` method of the next step; for example:
+The `draw()` method should accept an `image` parameter, which will be a native JavaScript image object (i.e. `new Image()`). 
+
+The draw method must, when it is complete, pass the output image to the method `options.output(image)`, which will send the output to the next module in the chain. For example:
 
 ```js
-function(image, onComplete) {
+function draw(image) {
 
   // do some stuff with the image
 
+  options.output(image);
+
 }
 ```

-> No, let's instead do: `module.draw()` and `module.setOutput(fn)` or `module.setNext(fn)`

 See existing module `green-channel` for an example: https://github.com/jywarren/image-sequencer/tree/master/src/modules/GreenChannel.js
