-  - `program(Component, {init, update, view})`: create a React program
+  - `program(Component, props => ({init, update, view}))`: create a React program
     - `Component`: a React Component class
-    - `init(props)`: return the initial state and optional effect
+    - `props`: the React component `props`

     - `view(state, dispatch)`: return the React view

 1. Define your messages with something like [`tagmeme`](https://github.com/andrejewski/tagmeme)
 1. Define your behaviors with `update(message, state)`
 1. Define your effects as functions which accept a dispatch function
