+Creates the directory structure for a tinc install:
 
+```
+/etc/tinc/{{netname}}/
+/etc/tinc/{{netname}}/tinc-up
+/etc/tinc/{{netname}}/tinc-down
+/etc/tinc/{{netname}}/tinc.conf
+/etc/tinc/{{netname}}/hosts/
+/etc/tinc/{{netname}}/hosts/{{ inventory_name }}
+/etc/tinc/{{netname}}/rsa_key.priv
+```
+
+The last one is a RSA 4096 private key, it may take a while to generate on low-entropy servers.
+
+It will also sync the ``playbook_dir/fetch/`` directory into
+``/etc/tinc/{{netname}}/hosts/``.
+
+
+# Expected group vars
+
+* **netname**: Name of the TINC network
+* **net_addr**: Address of the network
+* **net_cidr**: CIDR of the network (24 for me)
+* **default_connect**: Default node name to connect to (empty for a new network)
+
+Sample group_vars/all file:
+
+```yaml
+---
+
+netname: mynetwork
+net_addr: 10.11.12.0
+net_cidr: 24
+default_connect: mymachine
+```
+
+# Expected host vars
+
+**vpn_ip**: desired VPN internal ip of this host
+
+```
+[vpn_hosts]
+mymachine ansible_host=1.1.1.1 vpn_ip=10.11.12.23
+mymachine2 ansible_host=1.1.2.2 vpn_ip=10.11.12.23
