+Deprecated Library
+------------------
+
+Deprecated is Easy to Use
+`````````````````````````
+
+If you need to mark a function or a method as deprecated,
+you can use the ``@deprecated`` decorator:
+
+Save in a hello.py:
+
+.. code:: python
+
+    from deprecated import deprecated
+
+
+    @deprecated(version='1.2.1', reason="You should use another function")
+    def some_old_function(x, y):
+        return x + y
+
+
+    class SomeClass(object):
+        @deprecated(version='1.3.0', reason="This method is deprecated")
+        def some_old_method(self, x, y):
+            return x + y
+
+
+    some_old_function(12, 34)
+    obj = SomeClass()
+    obj.some_old_method(5, 8)
+
+
+And Easy to Setup
+`````````````````
+
+And run it:
+
+.. code:: bash
+
+    $ pip install Deprecated
+    $ python hello.py
+    hello.py:15: DeprecationWarning: Call to deprecated function (or staticmethod) some_old_function.
+    (You should use another function) -- Deprecated since version 1.2.0.
+      some_old_function(12, 34)
+    hello.py:17: DeprecationWarning: Call to deprecated method some_old_method.
+    (This method is deprecated) -- Deprecated since version 1.3.0.
+      obj.some_old_method(5, 8)
+
+
+You can document your code
+``````````````````````````
+
+Have you ever wonder how to document that some functions, classes, methods, etc. are deprecated?
+This is now possible with the integrated Sphinx directives:
+
+For instance, in hello_sphinx.py:
+
+.. code:: python
+
+    from deprecated.sphinx import deprecated
+    from deprecated.sphinx import versionadded
+    from deprecated.sphinx import versionchanged
+
+
+    @versionadded(version='1.0', reason="This function is new")
+    def function_one():
+        '''This is the function one'''
+
+
+    @versionchanged(version='1.0', reason="This function is modified")
+    def function_two():
+        '''This is the function two'''
+
+
+    @deprecated(version='1.0', reason="This function will be removed soon")
+    def function_three():
+        '''This is the function three'''
+
+
+    function_one()
+    function_two()
+    function_three()  # warns
+
+    help(function_one)
+    help(function_two)
+    help(function_three)
+
+
+The result it immediate
+```````````````````````
+
+Run it:
+
+.. code:: bash
+
+    $ python hello_sphinx.py
+
+    hello_sphinx.py:23: DeprecationWarning: Call to deprecated function (or staticmethod) function_three.
+    (This function will be removed soon) -- Deprecated since version 1.0.
+      function_three()  # warns
+
+    Help on function function_one in module __main__:
+
+    function_one()
+        This is the function one
+
+        .. versionadded:: 1.0
+           This function is new
+
+    Help on function function_two in module __main__:
+
+    function_two()
+        This is the function two
+
+        .. versionchanged:: 1.0
+           This function is modified
+
+    Help on function function_three in module __main__:
+
+    function_three()
+        This is the function three
+
+        .. deprecated:: 1.0
+           This function will be removed soon
