 Installing PyAMS application
 ============================
 
-PyAMS default installation is based on `Buildout <http://www.buildout.org>`_ utility. It's not mandatory to use a
-virtual environment, but it allows you to have a better control over your Python resources.
+**PyAMS** default installation is based on `Buildout <http://www.buildout.org>`_ utility.
+
+.. tip::
+
+    Take a look at virtualenv_. This tool provide isolated Python environments, which are more practical than installing packages systemwide.
+    They also allow installing packages without administrator privileges.
 
-Current PyAMS version is based and validated for Python 3.5; your Python environment must also include a C
-compiler as well as development headers for Python, *libjpeg*, *libpng*, *libfreetype*, *libxml2*, *libxslt* and
