+## Ansible Notes
+
+### Bootstraping Ansible
+
+To run ansible you need a couple of things.
+
+Control Node: Any machine with Ansible installed. You can run commands and playbooks
+
+Managed Node: Any machine with Ansible installed. You can run commands and playbooks
+
+Step 1. Managed Node: Modify visudo 
+
+Ansible needs to run commands as sudo without password
+
+`sudo visudo`
+
+Find and uncomment
+This line
+`%wheel ALL=(ALL) NOPASSWD: ALL`
+
+to:
+
+`wheel ALL=(ALL) NOPASSWD: ALL`
+
+
+Step 2. Control Node: ansible.cfg
+
+```
+[defaults]
+inventory = ./hosts.live
+remote_user = <THE USERNAME THAT IS GOING TO RUN Ansible Scripts>
+```
+
+Step 2. Managed Node: (SKIP if you already have one) Create an ssh key
+
+Add user ansible
+```
+sudo useradd ansible -m
+#add to wheel
+sudo usermod -aG wheel ansible
+```
+
+Create Key (this will create a key with no passphrase
+
+```bash
+ssh-keygen -t rsa -C "ansible@myremotemachine" -f "$(pwd)/keys/myremotemachine.id_rsa" -P ""
+```
+
+Add it to authorized_keys
+
+sudo mkdir /home/ansible/.ssh/
+sudo touch /home/ansible/.ssh/authorized_keys
+sudo chmod 700 /home/ansible/.ssh
+sudo chmod 700 /home/ansible/.ssh/authorized_keys
+sudo chown -R ansible:ansible /home/ansible
+sudo cat $(pwd)/keys/HOSTNAME.id_rsa.pub >> /home/ansible/.ssh/authorized_keys
+
+Step 3. Control Node: Add this key to host.live (Defined in ansible.cfg)
+
+```
+[myremotemachine]
+123.x.x.x
+
+[myremotemachine:vars]
+`ansible_ssh_private_key_file=keys/myremotemachine.id_rsa`
+```
+
+Step 4. Managed Node: Install Ansible 
+
+```
+wget --output-document /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py
+sudo python /tmp/get-pip.py
+sudo pip install ansible
+```
+
+Step 4. Control Node: Verify this by running ansible all -m ping 
+
+$ `ansible all -m ping`
+```bash
+myremotemachine | SUCCESS => {
+    "changed": false,
+    "ping": "pong"
+}
+```
