 ## Navigating between screens
 The navigation in Monarch is based around a stack of screens. When a screen is shown it is pushed to the top of the stack. When going back to a previous screen the topmost screen on the stack is removed. Example:
 
 * Showing screen A
-* Stack is [A]
+* Stack is ````[A]````
 * Showing screen B
-* Stack is [A, B] - (B is on top)
+* Stack is ````[A, B]```` - (B is on top)
 * Going back
-* Stack is [A]
+* Stack is ````[A]````
 
 ### Showing a new screen
 You show a screen in one of two ways:
 
 1. Post a ````show```` message to the ````screen.script````
-2. Call ````monarch.show(screen_id, [options], [data], [callback])````
+2. Call ````monarch.show()```` (see below)
 
 Showing a screen will push it to the top of the stack and trigger an optional transition. The previous screen will be hidden (with an optional transition) unless the screen to be shown is a [popup](#popups).
 
 #### Preventing duplicates in the stack
 You can pass an optional ````clear```` flag when showing a screen (either as a key value pair in the options table when calling ````monarch.show()```` or in the message). If the clear flag is set Monarch will search the stack for the screen in question. If the screen already exists in the stack and the clear flag is set Monarch will remove all screens between the current top and the screen in question. Example:
 
-* Stack is [A, B, C, D] - (D is on top)
+* Stack is ````[A, B, C, D]```` - (D is on top)
 * A call to ````monarch.show(B, { clear = true })```` is made
-* Stack is [A, B]
+* Stack is ````[A, B]````
 
 ### Going back to a previous screen
 You navigate back in the screen hierarchy in one of two ways:
 
 1. Post a ````back```` message to the ````screen.script````
-2. Call ````monarch.back()````
+2. Call ````monarch.back()```` (see below)

 ## Popups
 A screen that is flagged as a popup (see list of screen properties above) will be treated slightly differently when it comes to navigation. If a popup is at the top of the stack (ie currently shown) and another screen or popup is shown then the current popup will be removed from the stack. This means that it is not possible to have a popup anywhere in the stack but the top. This also means that you cannot navigate back to a popup since popups can only exist on the top of the stack. Another important difference between normal screens and popups is that when a popup is shown on top of a non-popup the current top screen will not be unloaded and instead remain visible in the background.

 * A call to ````monarch.show(D)````
-* Stack is [A, B, D]
+* Stack is ````[A, B, D]````
 
 ## Transitions
 You can add optional transitions when navigating between screens. The default behavior is that screen navigation is instant but if you have defined a transition for a screen Monarch will wait until the transition is completed before proceeding. The Transition Show In/Out and Transition Back In/Out properties described above should be URLs to one or more scripts with on_message handlers for the following messages:
