+## Prerequires
 
+To check if you're kernel can run kvm :
+
+    # kvm_ok or kvm-ok command (on Ubuntu at least)
     kvm_ok
+    # or look for vmx or svm in /proc/cpuinfo
+    egrep '^flags.*(vmx|svm)' /proc/cpuinfo
+
+The modules needed are the following : kvm, kvm_intel or kvm-amd.
+
+## Define a new box
+
+The workflow to create a box is almost the same as with the Virtualbox
+provider (and others).
+
+## Options
+
+There is currently few options supported :
+
+1. **network_type**: the type of network used by this box on libvirt. It could
+   be either _network_ (for using the default network) or _bridge_.
+2. **network_bridge_name**: the name of the bridge. It is used just in case
+   **network_type** is set to _bridge_.
+3. **pool_name**: the _storage_ pool name to be used when creating the box. If
+   not specified, the default one is used. _Note: it is currently not working
+   with the current fog version (1.7.0) but should be fixed as soon as the fog
+   gem is released_.
