+# Contributing
+
+Thank you for your interest! Sanic is always looking for contributors. If you
+don't feel comfortable contributing code, adding docstrings to the source files
+is very appreciated.
+
+## Installation
+
+To develop on sanic (and mainly to just run the tests) it is highly recommend to
+install from sources.
+
+So assume you have already cloned the repo and are in the working directory with
+a virtual environment already set up, then run:
+
+```bash
+python setup.py develop && pip install -r requirements-dev.txt
+```
+
+## Running tests
+
+To run the tests for sanic it is recommended to use tox like so:
+
+```bash
+tox
+```
+
+See it's that simple!
+
+## Pull requests!
+
+So the pull request approval rules are pretty simple:
+1. All pull requests must pass unit tests
+2. All pull requests must be reviewed and approved by at least 
+one current collaborator on the project
+3. All pull requests must pass flake8 checks
+4. If you decide to remove/change anything from any common interface
+a deprecation message should accompany it.
+5. If you implement a new feature you should have at least one unit
+test to accompany it.
+
+## Documentation
+
+Sanic's documentation is built
+using [sphinx](http://www.sphinx-doc.org/en/1.5.1/). Guides are written in
+Markdown and can be found in the `docs` folder, while the module reference is
+automatically generated using `sphinx-apidoc`.
+
+To generate the documentation from scratch:
+
+```bash
+sphinx-apidoc -fo docs/_api/ sanic
+sphinx-build -b html docs docs/_build
+```
+
+The HTML documentation will be created in the `docs/_build` folder.
+
+## Warning
+
+One of the main goals of Sanic is speed. Code that lowers the performance of
+Sanic without significant gains in usability, security, or features may not be
+merged. Please don't let this intimidate you! If you have any concerns about an
+idea, open an issue for discussion and help.

+# 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):

+
+            if is_authorized:
+                # the user is authorized.
+                # run the handler method and return the response
+                response = await f(request, *args, **kwargs)

+# Logging
+
+
+Sanic allows you to do different types of logging (access log, error log) on the requests based on the [python3 logging API](https://docs.python.org/3/howto/logging.html). You should have some basic knowledge on python3 logging if you want do create a new configuration.
+
+### Quck Start
+
+A simple example using default setting would be like this:
+
+```python
+from sanic import Sanic
+from sanic.config import LOGGING
+
+# The default logging handlers are ['accessStream', 'errorStream']
+# but we change it to use other handlers here for demo purpose
+LOGGING['loggers']['network']['handlers'] = [
+    'accessTimedRotatingFile', 'errorTimedRotationgFile']
+
+app = Sanic('test')
+
+@app.route('/')
+async def test(request):
+    return response.text('Hello World!')
+
+if __name__ == "__main__":
+  app.run(log_config=LOGGING)
+```
+
+After the program starts, it will log down all the information/requests in access.log and error.log in your working directory.
+
+And to close logging, simply assign log_config=None:
+
+```python
+if __name__ == "__main__":
+  app.run(log_config=None)
+```
+
+This would skip calling logging functions when handling requests.
+And you could even do further in production to gain extra speed:
+
+```python
+if __name__ == "__main__":
+  # disable internal messages
+  app.run(debug=False, log_config=None)
+```
+
+### Configuration
+
+By default, log_config parameter is set to use sanic.config.LOGGING dictionary for configuration. The default configuration provides several predefined `handlers`:
+
+- internal (using [logging.StreamHandler](https://docs.python.org/3/library/logging.handlers.html#logging.StreamHandler))<br>
+  For internal information console outputs.
+
+
+- accessStream (using [logging.StreamHandler](https://docs.python.org/3/library/logging.handlers.html#logging.StreamHandler))<br>
+  For requests information logging in console
+
+
+- errorStream (using [logging.StreamHandler](https://docs.python.org/3/library/logging.handlers.html#logging.StreamHandler))<br>
+  For error message and traceback logging in console.
+
+
+- accessSysLog (using [logging.handlers.SysLogHandler](https://docs.python.org/3/library/logging.handlers.html#logging.handlers.SysLogHandler))<br>
+  For requests information logging to syslog.
+  Currently supports Windows (via localhost:514), Darwin (/var/run/syslog),
+  Linux (/dev/log) and FreeBSD (/dev/log).<br>
+  You would not be able to access this property if the directory doesn't exist.
+  (Notice that in Docker you have to enable everything by yourself)
+
+
+- errorSysLog (using [logging.handlers.SysLogHandler](https://docs.python.org/3/library/logging.handlers.html#logging.handlers.SysLogHandler))<br>
+  For error message and traceback logging to syslog.
+  Currently supports Windows (via localhost:514), Darwin (/var/run/syslog),
+  Linux (/dev/log) and FreeBSD (/dev/log).<br>
+  You would not be able to access this property if the directory doesn't exist.
+  (Notice that in Docker you have to enable everything by yourself)
+
+
+- accessTimedRotatingFile (using [logging.handlers.TimedRotatingFileHandler](https://docs.python.org/3/library/logging.handlers.html#logging.handlers.TimedRotatingFileHandler))<br>
+  For requests information logging to file with daily rotation support.
+
+
+- errorTimedRotatingFile (using [logging.handlers.TimedRotatingFileHandler](https://docs.python.org/3/library/logging.handlers.html#logging.handlers.TimedRotatingFileHandler))<br>
+  For error message and traceback logging to file with daily rotation support.
+
+And `filters`:
+
+- accessFilter (using sanic.defaultFilter.DefaultFilter)<br>
+  The filter that allows only levels in `DEBUG`, `INFO`, and `NONE(0)`
+
+
+- errorFilter (using sanic.defaultFilter.DefaultFilter)<br>
+  The filter taht allows only levels in `WARNING`, `ERROR`, and `CRITICAL`
+
+There are two `loggers` used in sanic, and **must be defined if you want to create your own logging configuration**:
+
+- sanic:<br>
+  Used to log internal messages.
+
+
+- network:<br>
+  Used to log requests from network, and any information from those requests.
+
+#### Log format:
+
+In addition to default parameters provided by python (asctime, levelname, message),
+Sanic provides additional parameters for network logger with accessFilter:
+
+- host (str)<br>
+  request.ip
+
+
+- request (str)<br>
+  request.method + " " + request.url
+
+
+- status (int)<br>
+  response.status
+
+
+- byte (int)<br>
+  len(response.body)
+
+
+The default access log format is 
+```python
+%(asctime)s - (%(name)s)[%(levelname)s][%(host)s]: %(request)s %(message)s %(status)d %(byte)d
+```

+## 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())
+```

+decorator:
+
+```python
+async def feed(request, ws):
+    pass
+
+app.add_websocket_route(my_websocket_handler, '/feed')
+```
+
+Handlers for a WebSocket route are passed the request as first argument, and a
+WebSocket protocol object as second argument. The protocol object has `send`
+and `recv` methods to send and receive data respectively.
+
+WebSocket support requires the [websockets](https://github.com/aaugustin/websockets)
+package by Aymeric Augustin.

+# Streaming
+
+Sanic allows you to stream content to the client with the `stream` method. This method accepts a coroutine callback which is passed a `StreamingHTTPResponse` object that is written to. A simple example is like follows:
+
+```python
+from sanic import Sanic
+from sanic.response import stream
+
+app = Sanic(__name__)
+
+@app.route("/")
+async def test(request):
+    async def sample_streaming_fn(response):
+        response.write('foo,')
+        response.write('bar')
+
+    return stream(sample_streaming_fn, content_type='text/csv')
+```
+
+This is useful in situations where you want to stream content to the client that originates in an external service, like a database. For example, you can stream database records to the client with the asynchronous cursor that `asyncpg` provides:
+
+```python
+@app.route("/")
+async def index(request):
+    async def stream_from_db(response):
+        conn = await asyncpg.connect(database='test')
+        async with conn.transaction():
