+# Ansible-tools
+
+Just a repo for some handy Ansible playbooks. Just handy to save time and make installs uniform.
+
+## Install Ansible
+
+Unfortunately I can't make an Ansible playbook if you don't have it already installed on a machine:
+
+https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html
+
+## How it works
+
+Typical running is as follows:
+
+```
+ansible-playbook playbook.yml -K
+```
+
+If not as above check specific README for sub directory.
+
+## Playbooks:
+
+### docker-ce
+
+Simple playbook to install apt keys required, installs docker-ce and all dependencies
