+=========================
+
+Env-setup
+---------
+
+The 'env-setup' script modifies your environment to allow you to run
+tower-cli from a git checkout using python 2.6+.
+
+First, set up your environment to run from the checkout:
+
+    $ source ./hacking/env-setup
+
+You will need some basic prerequisites installed.  If you do not already have them
+and do not wish to install them from your operating system package manager, you
+can install them from pip
+
+    $ easy_install pip               # if pip is not already available
+    $ pip install -r requirements.txt
+
+From there, follow tower-cli instructions on docs.ansible.com as normal.
