+Strategies
+===========
+
+In 2.0 we added a new way to control play execution, ``strategy``, by default plays will
+still run as they used to, with what we call the ``linear`` strategy. All hosts will run each
+task befor any host starts the next task, using the number of forks (default 5) to paralelize.
+
+The ``serial`` directive can 'batch' this behaviour to a subset of the hosts, which then run to
+completion of the play before the next 'batch' starts.
+
+A second ``strategy`` ships with ansible ``free``, which allows each host to run until the end of
+the play as fast as it can.::
+
+    - hosts: all
+      strategy: free
+      tasks:
+      ...

+Stratergy Plugins
+`````````````````
+
+The strategies are implelented via a new type of plugin, this means that in the future new
+execution types can be added in the future, either locally by users or to Ansible itself by
+a code contribution.
