-When invoking `$.fn.pjax` there are a few different argument styles you can use:
+#### Arguments
 
-1. `$(document).pjax(delegation selector, options object)`
-2. `$(document).pjax(delegation selector, container selector, options object)`
+The synopsis for the `$.fn.pjax` function is:
 
-In other words:
+``` javascript
+$(document).pjax(selector, [container], options)
+```
+
+1. `selector` is a string to be used for click [event delegation][$.fn.on].
+2. `container` is a string selector that uniquely identifies the pjax container.
+3. `options` is an object with keys described below.
+
+##### pjax options
+
+key | default | description
+----|---------|------------
+`timeout` | 650 | ajax timeout in milliseconds after which a full refresh is forced
+`push` | true | use [pushState][] to add a browser history entry upon navigation
+`replace` | false | replace URL without adding browser history entry
+`maxCacheLength` | 20 | maximum cache size for previous container contents
+`version` | | a string or function returning the current pjax version
+`scrollTo` | 0 | vertical position to scroll to after navigation
+`type` | `"GET"` | see [$.ajax][]
+`dataType` | `"html"` | see [$.ajax][]
+`container` | | CSS selector for the element where content should be replaced
+`url` | link.href | a string or function that returns the URL for the ajax request
+`target` | link | eventually the `relatedTarget` value for [pjax events](#events)
+`fragment` | `"body"` | CSS selector for the fragment to extract from ajax response
+
+You can change the defaults globally by writing to the `$.pjax.defaults` object:
 
-1. The first argument must always be a `String` selector used for delegation.
-2. The second argument can either be a `String` container selector or an options object.
-3. If there are three arguments the second must be the `String` container selector and the third must be the options object.
+``` javascript
+$.pjax.defaults.timeout = 1200
