 Whilst SFINV by default shows pages as tabs, pages are called "pages" as
 it's entirely possible that a mod or game decides to show them in
 some other format instead.
+For example, multiple pages could be shown on one view.

 ## Registering a Page
 
-So, to register a page you need to call the aptly named `sfinv.register_page`
-function with the page's name, and its definition. Here is a minimal example:
-
-```lua
-sfinv.register_page("mymod:hello", {
-    title = "Hello!",
-    get = function(self, player, context)
-        -- TODO: implement this
-    end
-})
-```
-
-You can also override an existing page using `sfinv.override_page`.
-
-If you ran the above code and clicked the page's tab, it would probably crash
-as sfinv is expecting a response from the `get` method. So let's add a response
-to fix that:
+SFINV provides the aptly named `sfinv.register_page` function to create pages.

 ## on_enter and on_leave callbacks
 
-You can run code when a player enters (your tab becomes selected) or
-leaves (another tab is about to be selected) your tab.
+A player *enters* a tab when the tab is selected, and *leaves* a
+tab when another tab is about to be selected.
+It's possible for multiple pages to be selected if a custom theme is
+used.
 
-Please note that you can't cancel these, as it would be a bad user experience
-if you could.
+Note that these events may not be triggered by the player.
+The player may not even have the formspec open at that time.
+For example, on_enter is called for the home page when a player
+joins the game even before they open their inventory.
 
-Also, note that the inventory may not be visible at the time
-these callbacks are called. For example, on_enter is called for the home page
-when a player joins the game even before they open their inventory!
+It's not possible to cancel a page change, as that would potentially
+confuse the player.
