 ## Shepherd
@@ -9,46 +8,179 @@ Guide your users through a tour of your app.
 ### Dependencies
 
 Shepherd uses [Tether](http://github.hubspot.com/tether/docs/welcome) to
-position each step container. You can [download Tether here](https://github.com/HubSpot/tether/releases).
+position each step container.  Tether is included in the `shepherd.js` and `shepherd.min.js` files.
 
-### Usage
+Otherwise, none!
 
-Using `Shepherd` is really easy.
+### Usage
 
-First create a new `Shepherd` instance.
+First create a new `Tour` instance for your tour:
 
 ```coffeescript
-shepherd = new Shepherd
+tour = new Shepherd.Tour
   defaults:
-    classes: 'shepherd-element shepherd-open shepherd-theme-arrows'
+    classes: 'shepherd-theme-arrows'
     scrollTo: true
 ```
 
- The main options you'll want to
-set are the class names to be added to each step. To use the default
-theme `shepherd-theme-arrows`, set `classes` to `"shepherd shepherd-open shepherd-theme-arrows"`.
-Also, you'll want to set `scrollTo` to `true` if you want Shepherd to try to
-scroll to step targets when it advances from one step to another.
+The `defaults` option allows you to specify any options which should be applied
+to all this tour's steps by default.
 
-After creating an instance to work with, you'll add steps for each target you want. You can name steps if you want to be able shortcut to them later.
+Next, add your steps:
 
 ```coffeescript
-shepherd.addStep 'example-step',
+tour.addStep 'example-step',
   text: 'This step is attached to the bottom of the <code>.example-css-selector</code> element.'
   attachTo: '.example-css-selector bottom'
   classes: 'example-step-extra-class'
   buttons: [
     text: 'Next'
-    action: shepherd.next
+    action: tour.next
   ]
 ```
 
-Finally, to start the tour, just call `start`.
+Finally, to start the tour, just call `start` on your `Tour` instance:
 
 ```coffeescript
-shepherd.start()
+tour.start()
+```
+
+### API
+
+#### Global Shepherd Object
+
+Shepherd exposes a single object onto the window, `Shepherd`.
+
+That global object fires several events to let you link up actions with events
+occuring in _any_ tour:
+
+##### Methods
+
+- `Shepherd.on(eventName, handler, [context])`: Bind an event
+- `Shepherd.off(eventName, [handler])`: Unbind an event
+- `Shepherd.once(eventName, handler, [context])`: Bind just the next instance of an event
+
+##### Events
+
+The global Shepherd fires the following events whenever a `Tour` instance fires them.  It adds to the object passed to the
+event handlers a `tour` key pointing to the instance which fired the event:
+
+- `complete`
+- `cancel`
+- `hide`
+- `show`
+- `start`
+
+##### Current Tour
+
+The global `Shepherd` includes a property which is always set to the currently active tour, or null if there is no active tour:
+
+- `Shepherd.activeTour`
+
+#### Tour Instances
+
+##### Creation
+
+You create a `Tour` object for each tour you'd like to create.
+
+Tour's constructor accepts a hash of options:
+
+```javascript
+myTour = new Shepherd.Tour({ options })
+```
+
+##### Tour Options
+
+- `steps`: An array of Step instances to initialize the tour with
+- `defaults`: Default options for Steps created through `addStep`
+
+##### Tour Methods
+
+- `addStep(id, options)`: Creates a new Step object with options.  If you'd like you can also just pass an options hash which includes `id` as a key.
+You can also pass an existing `Step` instance rather than `options`, but note that Shepherd does not support a Step being attached to multiple Tours.
+- `getById(id)`: Return a step with a specific id
+- `next()`: Advance to the next step, in the order they were added
+- `back()`: Show the previous step, in the order they were added
+- `cancel()`: Trigger cancel on the current step, hiding it without advancing
+- `hide()`: Hide the current step
+- `show([id])`: Show the step specified by id (if it's a string), or index (if it's a number) provided.  Defaults to the first step.
+- `start()`: Show the first step and begin the tour
+- `getCurrentStep()`: Returns the currently shown step
+- `on(eventName, handler, [context])`: Bind an event
+- `off(eventName, [handler])`: Unbind an event
+- `once(eventName, handler, [context])`: Bind just the next instance of an event
+
+##### Tour Events
+
+- `complete`: Triggered when the last step is advanced
+- `cancel`
+- `hide`
+- `show`: Triggered with a hash of the `step` and the `previous` step
+- `start`
+
+Steps are instances of the Step object.  They are generally created by the `Tour::addStep` method, which returns the `Step` instance its
+created.
+
+#### Steps
+
+##### Step Options
+
+- `text`: The text in the body of the step.  It can either be an HTML string, or an array of
+strings, each of which will become a `<p>` paragraph.
+- `title`: The steps title.  It becomes an `h3` at the top of the step.
+- `attachTo`: What element the step should be attached to on the page.  It can either be a string of the form
+`"element on"`, or an object with those properties.  For example: `".some #element left"`, or `{element: '.some #element',
+on: 'left'}`.  If you use the object syntax, `element` can also be a DOM element.  If you don't specify an `attachTo`
+the element will appear in the middle of the screen.
+- `classes`: Extra classes to add to the step.  `shepherd-theme-arrows` will give you our theme.
+- `buttons`: An array of buttons to add to the step.  By default we add a Next button which triggers `next()`, set this to false
+to disable.  Each button in the array is an object of the format:
+  - `text`: The HTML text of the button
+  - `classes`: Extra classes to apply to the `<a>`
+  - `action`: A function executed when the button is clicked on
+  - `events`: A hash of events to bind onto the button, for example `{'mouseover': function(){}}`.  Adding a click event to `events` when you
+  already have an `action` specified is not supported.
+- `advanceOn`: An action which should advance shepherd to the next step.  It can be of the form `"event selector"`, or an object with those
+properies.  For example: `"click .some-element"`, or `{element: '.some-element', event: 'click'}`.  You can also always manually advance the
+Tour by calling `myTour.next()`.
+- `scrollTo`: Should the element be scrolled to when this step is shown?
+
+##### Step Methods
+
+- `show()`: Show this step
+- `hide()`: Hide this step
+- `cancel()`: Hide this step and trigger the `cancel` event
+- `complete()`: Hide this step and trigger the `complete` event
+- `scrollTo()`: Scroll to this step's element
+- `isOpen()`: Returns true if the step is currently shown
+- `destroy()`: Remove the element
+- `on(eventName, handler, [context])`: Bind an event
+- `off(eventName, [handler])`: Unbind an event
+- `once(eventName, handler, [context])`: Bind just the next instance of an event
+
+##### Step Events
+
+- `show`
+- `hide`
+- `complete`
+- `cancel`
+- `destroy`
+
+Please note that `complete` and `cancel` are only ever triggered if you call the associated methods in your code.
+
+### Advancing on Actions
+
+You can use the `advanceOn` option, or the Next button, to advance steps.  If you would like however to have a step advance on a
+complex user action, you can do the following:
+
+```coffeescript
+myStep = myTour.addStep 'my-step', options
+
+yourApp.on 'some-event', ->
+  if myStep.isOpen()
+    Shepherd.activeTour.next()
 ```
