+### Install ansible system wide
+
+Follow the [instructions to install the latest version of Ansible][ansible-install].
+* In most cases, using pip: `pip install ansible`.
+* If you use brew, then `brew install python2 ansible`, and then run
+`export PYTHONPATH=$(pip2 show pyyaml | grep Location | awk '{print $2}') `
+before you use `ansible-playbook`.
+
+### Install ansible in virtualenv
+
+From the `ansible` directory:
+
+1. Run `make && make UPDATE_ENV`
+2. Run `source ./virtualenv/bin/activate` to activate the virtualenv
+3. You can now use `ansible-playbook`
+4. When done you can quit the virtualenv with `deactivate`
+
+**NOTE**: Virtualenv is now set to use _ansible 2.4.0_
