+### **Provision with** ***Ansible***
+you want to **create an _Ansible_ control node** and that is as simple as
+installing a package onto your machine. Ansible is built using python
+which makes it easy to install as **we can use the python pip package
+manger.** To check you have it installed do ```pip --version``` if
+it's not installed do the following
+
+
+```curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py```
+
+```python get-pip.py --user```
+
+**once you have pip installed proceed to installing _Ansible_**
+
+[Docs](https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html)
+
+```pip install ansible```
+
+Now that ansible is installed we can create a runbok that defines the
+steps ansible needs to take on the remote machine to correctly
+provision it. This playbook is written in yaml so get ready to make
+sure your indents are correct 😬

+**Creating the playbook**
+now you can copy what I have and it should work - after changing a
+thing or two - which is fine however I encourage you to copy what I
+have, read the [Docs](https://docs.ansible.com/ansible/latest/user_guide/index.html)
+and make any changes you feel are necessary.
