 Getting Started
 +++++++++++++++
 
-Get Python 3.5
-==============
+Python 3.5 (or higher) only
+===========================
 
-Sorry but this documentation is written for Python 3.5 to avail of the new
-``async``
-and ``await`` keywords.
+This documentation is written for Python 3.5 to avail of the new
+``async`` and ``await`` keywords.
+
+If you have Python 3.5 installed you only need to install ``aiohttp``::
+
+    pip install -U aiohttp
+
+If you don't have Python 3.5 installed yet, you have several options
+to install it.
+
+All platforms with ``conda``
+----------------------------
+
+* Download and install
+  `Miniconda <http://conda.pydata.org/miniconda.html>`_  for our platform.
+* Create a new Python 3.5 environment (named ``aio35``, use a different
+  if you like)::
+
+       conda create -n aio35 python=3.5
+
+* Activate it.
+  Linux and OS X::
+
+       $ source activate aio35
+
+  Windows::
+
+       $ source activate aio35
+
+* Install ``aiohttp``::
+
+       $(aio35) pip install aiohttp
+
+Platform specific
+-----------------
 
 .. would be good to have some word about installing on Windows
-* Windows: the easiest way to use Python 3.5 would be to use a package manager
-  like Conda
-  There are instructions for using a python 3.5 environment in `Conda here
-  <http://conda.pydata.org/docs/py2or3.html#create-a-python-3-5-environment>`_.
-* Mac OS X: install `Homebrew </usr/bin/ruby -e "$(curl -fsSL
+* Windows: The easiest way to use Python 3.5 would be to use a package manager
+  such as conda. See the installation instructions above.
+* Mac OS X: Install `Homebrew </usr/bin/ruby -e "$(curl -fsSL
   https://raw.githubusercontent.com/Homebrew/install/master/install)">`_ and
-  then type ``brew install python3``
+  then type ``brew install python3``-
 * Linux: Ubuntu 16.04+ and Arch linux ship with Python 3.5 included.
   If you don't have Python 3.5+ on your computer, you can compile it or use
-  `Pythonz <https://github.com/saghul/pythonz>`_
+  `Pythonz <https://github.com/saghul/pythonz>`_.
 
 
 Create a virtual environment to run examples
 ============================================
 
-Create a virtual environment::
+If you don't use conda (see above), create a virtual environment::
 
     python3 -m venv venv
 
 .. note::
-    Depending on your platform, the python 3 interpreter could be invoked by
-    ``python`` instead. This is the case for Conda on Windows for example.
