-Playbook for base and initial configuration of web server hosting my personal websites.
+# Ansible Playbook
 
-### To use
-Create a new Ubuntu 14.04 host, add a user account, copy your SSH public key, then execute:
+Ansible playbook for base and initial configuration of web server hosting my personal websites.  After successful execution of this playbook, however, there is still some manual work to import databases, copy site content, etc.
 
-    ansible-playbook site.yml -i hosts --limit=web01 -K
+## Assumptions
+Before you can run this, a few things are assumed:
 
-### Testing
-For testing, use a VM, ie with KVM and libvirt:
+- You have a clean, minimal Ubuntu 14.04 host up and running
+- You have a user account with password-less SSH access to the machine
+- You have sudo privileges on the remote host
+- You have created a `hosts` file with something like:
+
+```ini
+[web]
+web01
+```
+
+## Use
+Once you've satisfied the the above assumptions, you can execute:
+
+    ansible-playbook web.yml -i hosts -K
+
+### Testing in a VM
+A simple way to test locally in a virtual machine using libvirt + KVM:
 
 ```console
-virt-install -n web01 -r 1024 --vcpus 2 -l http://ubuntu.mirror.ac.ke/ubuntu/dists/trusty/main/installer-amd64/ --os-type=linux --os-variant=ubuntusaucy --disk /home/aorth/software/vms/web01.qcow2,device=disk,bus=virtio,format=qcow2,size=40 --vnc --cpuset=1,2 -x "auto=true priority=critical url=http://blah.com/~aorth/preseed/public/ubuntu-14.04.cfg"
+sudo virt-install -n web01 -r 1024 --vcpus 2 -l http://ubuntu.mirror.ac.ke/ubuntu/dists/trusty/main/installer-amd64/ --os-type=linux --os-variant=ubuntusaucy --disk /home/aorth/software/vms/web01.qcow2,device=disk,bus=virtio,format=qcow2,size=40 --vnc --cpuset=1,2 -x "auto=true priority=critical url=http://blah.com/~aorth/preseed/public/ubuntu-14.04.cfg"
 ```
+
+This boots from a network Ubuntu mirror, then uses a preseed to automate the OS installtion.
