+This directory is for [ansible](http://www.ansible.com/home) playbooks for sysadmin tasks around unglue.it.
+
+We start with automating tasks such as [applying security upgrades](unattended-upgrade.yml) to the servers.
+
+Goal is to build playbooks for the configuration of servers.
+
+# Current status of playbooks
+
+* [host](hosts) is currently written by hand -- the inventory might be dynamically generated at some point.
+
+
+# Installing ansible
+
+[installation instructions](http://docs.ansible.com/intro_installation.html).
+
+On the mac, easiest approach is probably to use [homebrew](http://brew.sh/):
+
+    brew install ansible
+    
+You can also use `pip`:
+
+    pip install ansible
+    
+Note: ansible depends on one having ssh access to the servers.
+
+
+# Running unattended-upgrade
+
+in `regluit/sysadmin/playbooks`, run
+
+    ansible-playbook -i hosts -e "target=instances" unattended-upgrade.yml
+    
+to run on all the servers.
+
+    ansible-playbook -i hosts unattended-upgrade.yml
+    
+will run only just.

+Role Name
+=========
+
+A brief description of the role goes here.
+
+Requirements
+------------
+
+Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
+
+Role Variables
+--------------
+
+A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
+
+Dependencies
+------------
+
+A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
+
+Example Playbook
+----------------
+
+Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
+
+    - hosts: servers
+      roles:
+         - { role: username.rolename, x: 42 }
+
+License
+-------
+
+BSD
+
+Author Information
+------------------
+
+An optional section for the role authors to include contact information, or a website (HTML is not allowed).
