 ## Registering a callback
 
 Modules can use Synapse's module API to register callbacks. Callbacks are functions that
-Synapse will call when performing specific actions. Callbacks must be asynchronous (unless
-specified otherwise), and are split in categories. A single module may implement callbacks
-from multiple categories, and is under no obligation to implement all callbacks from the
-categories it registers callbacks for.

 Modules can register callbacks using one of the module API's `register_[...]_callbacks`
 methods. The callback functions are passed to these methods as keyword arguments, with
-the callback name as the argument name and the function as its value. A
-`register_[...]_callbacks` method exists for each category.

 Callbacks for each category can be found on their respective page of the
