-Install pip
-===========
-
-pip is the easiest way to install psutil. It is shipped by default with Python
-2.7.9+ and 3.4+. For other Python versions you can install it manually.
-On Linux or via wget::
-
-    wget https://bootstrap.pypa.io/get-pip.py -O - | python
+Linux, Windows, macOS (wheels)
+==============================
 
-On macOS or via curl::
-
-    python < <(curl -s https://bootstrap.pypa.io/get-pip.py)
-
-On Windows, `download pip <https://pip.pypa.io/en/latest/installing/>`__, open
-cmd.exe and install it::
+psutil makes extensive use of C extension modules, meaning a C compiler is
+required.
+For these 3 platforms though, pre-compiled cPython wheels are provided on each
+psutil release, so all you have to do is this::
 
-    C:\Python27\python.exe get-pip.py
-
-Permission issues (UNIX)
-========================
-
-The commands below assume you're running as root.
-If you aren't or you bump into permission errors you can either install psutil
-for your user only::
-
-    pip3 install --user psutil
-
-...or prepend ``sudo`` and install it globally, e.g.::
+    pip3 install psutil
 
-    sudo pip3 install psutil
+If wheels are not available and you whish to install from sources, keep reading.
 
-Linux
-=====
+Linux (install from sources)
+============================
 
 Ubuntu / Debian::
 
     sudo apt-get install gcc python3-dev
-    pip3 install psutil
+    pip3 install --user psutil --no-binary :all:
 
 RedHat / CentOS::
 
     sudo yum install gcc python3-devel
-    pip3 install psutil
-
-If you're on Python 2 use ``python-dev`` instead.
-
-macOS
-=====
+    pip3 install --user psutil --no-binary :all:
 
-Install `Xcode <https://developer.apple.com/downloads/?name=Xcode>`__ then run::
-
-    pip3 install psutil
-
-Windows
-=======
-
-Open a cmd.exe shell and run::
-
-    python3 -m pip install psutil
+Windows (install from sources)
+==============================
 
-This assumes "python" is in your PATH. If not, specify the full python.exe
-path.
+In order to compile psutil on Windows you'll need **Visual Studio**.
+Here's a couple of guides describing how to do it: `1 <https://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/>`__
+and `2 <https://cpython-core-tutorial.readthedocs.io/en/latest/build_cpython_windows.html>`__. And then::
 
-In order to compile psutil from sources you'll need **Visual Studio** (Mingw32
-is not supported).
-This  `blog post <https://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/>`__
-provides numerous info on how to properly set up VS. The needed VS versions are:
+    pip3 install --user psutil --no-binary :all:
 
-* Python 2.6, 2.7: `VS-2008 <http://www.microsoft.com/en-us/download/details.aspx?id=44266>`__
-* Python 3.4: `VS-2010 <http://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express>`__
-* Python 3.5+: `VS-2015 <http://www.visualstudio.com/en-au/news/vs2015-preview-vs>`__
-
-Compiling 64 bit versions of Python 2.6 and 2.7 with VS 2008 requires
-`Windows SDK and .NET Framework 3.5 SP1 <https://www.microsoft.com/en-us/download/details.aspx?id=3138>`__.
-Once installed run `vcvars64.bat`
-(see `here <http://stackoverflow.com/questions/11072521/>`__).
-Once VS is setup open a cmd.exe shell, cd into psutil directory and run::
-
-    python3 setup.py build
-    python3 setup.py install
+Note that MinGW compiler is not supported.
