 Sanic is a **Python 3.6+** web server and web framework that's written to go fast. It allows the usage of the ``async/await`` syntax added in Python 3.5, which makes your code non-blocking and speedy.
 
+Sanic is also ASGI compliant, so you can deploy it with an `alternative ASGI webserver <https://sanic.readthedocs.io/en/latest/sanic/deploying.html#running-via-asgi>`_.

+From file, dict, or any object (having __dict__ attribute).
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can store app configurations in: (1) a Python file, (2) a dictionary, or (3) in some other type of custom object.
+
+In order to load configuration from ove of those, you can use ``app.upload_config()``.
+
+**1) From file**
+
+
+Let's say you have ``my_config.py`` file that looks like this:
+
+.. code-block:: python
+
+    # my_config.py
+    A = 1
+    B = 2
+
+Loading config from this file is as easy as:
+
+.. code-block:: python
+
+    app.update_config("/path/to/my_config.py")
+ 
+You can also use environment variables in the path name here.
+
+Let's say you have an environment variable like this:
+
+.. code-block:: shell
+
+    $ export my_path="/path/to"
+    
+Then you can use it like this:
+
+.. code-block:: python
+
+    app.update_config("${my_path}/my_config.py")
+
+.. note::
+
+    Just remember that you have to provide environment variables in the format ${environment_variable} and that $environment_variable is not expanded (is treated as "plain" text).
+
+**2) From dict**
+
+You can also set your app config by providing a ``dict``:
+
+.. code-block:: python
+
+    d = {"A": 1, "B": 2}
+    
+    app.update_config(d)
+ 
+**3) From _any_ object**
+
+App config can be taken from an object. Internally, it uses ``__dict__`` to retrieve keys and values.
+
+For example, pass the class:
+
+.. code-block:: python
+
+    class C:
+        A = 1
+        B = 2
+        
+    app.update_config(C)
+
+or, it can be instantiated:
+
+.. code-block:: python
+
+    c = C()
+    
+    app.update_config(c)
+

 Usually you will want to load configuration from a file that is not part of the distributed application. You can load configuration from a file using `from_pyfile(/path/to/config_file)`.
