-Setting up an Environment
--------------------------
-
-The first thing you'll need is the Python ``virtualenv`` package. You probably already
-have this, but if not, you can install it with::
-
-  pip install -U virtualenv
-
-Once that's done, choose a location for the environment, and create it with the ``virtualenv``
-command. For our guide, we're going to choose ``/www/lemur/``::
-
-  virtualenv /www/lemur/
-
-Finally, activate your virtualenv::
-
-  source /www/lemur/bin/activate
-
-.. note:: Activating the environment adjusts your PATH, so that things like pip now
-          install into the virtualenv by default.

 Installing build dependencies
 -----------------------------
 
 If installing Lemur on truely bare Ubuntu OS you will need to grab the following packages so that Lemur can correctly build it's
 dependencies::

+
     $ sudo apt-get update
-    $ sudo apt-get install nodejs-legacy python-pip libpq-dev python-dev build-essential libssl-dev libffi-dev nginx git supervisor

+
+In this guide Lemur will be installed in ``/www``, so you need to create that structure first::
+
+.. code-block:: bash
+
+    $ sudo mkdir /www
+    $ cd /www
+
+Clone Lemur inside this directory and give your user permission to write in it (assume your user is lemur here)::
+
+.. code-block:: bash
+
+    $ sudo git clone https://github.com/Netflix/lemur
+    $ sudo chown -R lemur lemur/

 Installing from Source
 ~~~~~~~~~~~~~~~~~~~~~~
 
-If you're installing the Lemur source (e.g. from git), you'll also need to install **npm**.

 Once your system is prepared, ensure that you are in the virtualenv:

 And then run:
 
 .. code-block:: bash
 
   $ make develop
