 Message handlers
 ~~~~~~~~~~~~~~~~
 
-A message handler is a function which is decorated with the
-``message_handler`` decorator of a TeleBot instance. The following
-examples illustrate the possibilities of message handlers:
+A message handler is a function that is decorated with the
+``message_handler`` decorator of a TeleBot instance. Message handlers
+consist of one or multiple filters. Each filter much return True for a
+certain message in order for a message handler to become eligible to
+handle that message. A message handler is declared in the following way
+(provided ``bot`` is an instance of TeleBot):
+
+.. code:: python
+
+    @bot.message_handler(filters)
+    def function_name(message):
+        bot.reply_to(message, "This is a message handler")
+
+``function_name`` is not bound to any restrictions. Any function name is
+permitted with message handlers. The function must accept at most one
+argument, which will be the message that the function must handle.
+``filters`` is a list of keyword arguments. A filter is declared in the
+following manner: ``name=argument``. One handler may have multiple
+filters. TeleBot supports the following filters:

 Using webhooks
----------------
+--------------
 
-If you prefer using web hooks to the getUpdates method, you can use the
-``process_new_messages(messages)`` function in TeleBot to make it
-process the messages that you supply. It takes a list of Message
-objects. This function is still incubating.
+When using webhooks telegram sends one Update per call, for processing
+it you should call process\_new\_messages([update.message]) when you
+recieve it.
+
+There are some examples using webhooks in the
+*examples/webhook\_examples* directory.
 
 Logging
 -------
 
 You can use the Telebot module logger to log debug info about Telebot.
-Use ``telebot.logger`` to get the logger of the TeleBot module.
+Use ``telebot.logger`` to get the logger of the TeleBot module. It is
