## Definition of the state
|
||||

|
||||
import { Updux } from 'updux';

||||
import Updux from 'updux';

||||
## Add actions
|
||||
|
||||
This is all good, but a little static. Let's add actions!

```js

import { createAction } from 'updux';

### Accessing actions
|
||||
|
||||
Once an action is defined, its creator is accessible via the `actions` accessor.
|
||||
|
||||
This is not yet terribly exciting, but it'll get better once we begin using
|
||||
subduxes.
|
||||
```js
|
||||
console.log( todosDux.actions.addTodo('write tutorial') );

||||
// prints { type: 'addTodo', payload: 'write tutorial' }

||||
// => { type: 'addTodo', payload: 'write tutorial' }
