 Plugins in Lektor are based on the concept of hooking events.  There are many
 events that can be hooked but we will only cover a very basic one here,

 This will inject a function with the name `get_random_message` into our
-template context whenever a template is rendered.  This means that we
+template globals when the environment is initialized.  This means that we
 can access this function from templates then:
 
 ```html+jinja
