+# Handler Decorators
+
+Since Sanic handlers are simple Python functions, you can apply decorators to them in a similar manner to Flask. A typical use case is when you want some code to run before a handler's code is executed. 
+
+## Authorization Decorator
+
+Let's say you want to check that a user is authorized to access a particular endpoint. You can create a decorator that wraps a handler function, checks a request if the client is authorized to access a resource, and sends the appropriate response.
+
+
+```python
+from functools import wraps
+from sanic.response import json
+
+def authorized():
+    def decorator(f):
+        @wraps(f)
+        async def decorated_function(request, *args, **kwargs):
+            # run some method that checks the request
+            # for the client's authorization status
+            is_authorized = check_request_for_authorization_status(request)
+
+            if is_authorized:
+                # the user is authorized.
+                # run the handler method and return the response
+                response = await f(request, *args, **kwargs)
+                return response
+            else:
+                # the user is not authorized.

 Middleware are functions which are executed before or after requests to the

 user-defined handler functions.

+
+## Listeners
+
+If you want to execute startup/teardown code as your server starts or closes, you can use the following listeners:
+
+- `before_server_start`
+- `after_server_start`
+- `before_server_stop`
+- `after_server_stop`
+
+These listeners are implemented as decorators on functions which accept the app object as well as the asyncio loop. 
+
+For example:
+
+```python
+@app.listener('before_server_start')
+async def setup_db(app, loop):
+    app.db = await db_setup()
+
+@app.listener('after_server_start')
+async def notify_server_started(app, loop):
+    print('Server successfully started!')
+
+@app.listener('before_server_stop')
+async def notify_server_stopping(app, loop):
+    print('Server shutting down!')
+
+@app.listener('after_server_stop')
+async def close_db(app, loop):
+    await app.db.close()
+```
+
+If you want to schedule a background task to run after the loop has started,
+Sanic provides the `add_task` method to easily do so.
+
+```python
+async def notify_server_started_after_five_seconds():
+    await asyncio.sleep(5)
+    print('Server successfully started!')
+
+app.add_task(notify_server_started_after_five_seconds())
