+Key Features
+============
+
+- Supports both client and server side of HTTP protocol.
+- Supports both client and server Web-Sockets out-of-the-box and avoids
+  Callback Hell.
+- Provides Web-server with middlewares and plugable routing.
+
+
+Getting started
+===============
+
+Client
+------
+
+To get something from the web:
+
+.. code-block:: python
+
+  import aiohttp
+  import asyncio
+
+  async def main():
+
+      async with aiohttp.ClientSession() as session:
+          async with session.get('http://python.org') as response:
+
+              print("Status:", response.status)
+              print("Content-type:", response.headers['content-type'])
+
+              html = await response.text()
+              print("Body:", html[:15], "...")
+
+  loop = asyncio.get_event_loop()
+  loop.run_until_complete(main())
+
+This prints:
+
+.. code-block::
+
+    Status: 200
+    Content-type: text/html; charset=utf-8
+    Body: <!doctype html> ...
+
+Coming from `requests <https://requests.readthedocs.io/>`_ ? Read `why we need so many lines <https://aiohttp.readthedocs.io/en/latest/http_request_lifecycle.html>`_.
+
+Server
+------
+
+An example using a simple server:
+
+.. code-block:: python
+
+    # examples/server_simple.py
+    from aiohttp import web
+
+    async def handle(request):
+        name = request.match_info.get('name', "Anonymous")
+        text = "Hello, " + name
+        return web.Response(text=text)
+
+    async def wshandle(request):
+        ws = web.WebSocketResponse()
+        await ws.prepare(request)
+
+        async for msg in ws:
+            if msg.type == web.WSMsgType.text:
+                await ws.send_str("Hello, {}".format(msg.data))
+            elif msg.type == web.WSMsgType.binary:
+                await ws.send_bytes(msg.data)
+            elif msg.type == web.WSMsgType.close:
+                break
+
+        return ws
+
+
+    app = web.Application()
+    app.add_routes([web.get('/', handle),
+                    web.get('/echo', wshandle),
+                    web.get('/{name}', handle)])
+
+    if __name__ == '__main__':
+        web.run_app(app)
