+# VM setup
+This repo uses ansible to make the git setup (and potential further service deployments) 
+comprehensible for future maintenance.
+
+It is a basic ansible repo with to main roles:
+* libvirt for vm creation
+
+Other services could be added as further roles.
+
+## The playbooks
+Ansible uses playbooks, to configure the hardware as wished. The roles should be indempotent 
+and could be run arbitraryly often.
+
+### The libvirt setup
+The role installs `libvirt` on the vmhost and uses `virt-install` and _debian cloud images_
+to create the vms.
+
+Run it with
+
+    ansible-playbook -D create-vm.yml
+
+It asks the user a few questions and create a new entry for the new vm in this repository.
+Please push it to master afterwards.
+
+## Vaults
+Sensible information is encrypted and stored inside a so called _vault_.
+One example is `roles/git/vars/vault`
+It is decrypted on the fly, when using a playbook. To be able to decrypt the vault, you
+need a password file called `vault_pass` which has to be copied manually into the repo.
+It is explicitly excluded from git.
+Ask Carl for `vault_pass`.
+
+Use `ansible-vault` to mess around with the vault files manually.
