 # Hydra Suite - Command and Control
 
 Hydra is a suite for orchestration and management of machines composed of
-the following basic commands:
+**lots of conventions and assumptions**, and the following basic commands:
 
 * `hydractl`: act in the current host.
 * `hydra`:    act on at set of hosts.
 * `hydras`:   act on a superset of hosts.
 
-Check also the [slides](slides) (portuguese only).
+An Hydra is not a "cloud computing" platform, it's something else: a set of
+systems that operate together, where any node can be used to spawn new nodes.
+
+This is an ongoing experiment is how a person or a collective can manage
+many computers in an unified way. It's not production ready, and it always
+struggles to pass the test of time.
+
+Running the Hydra Suite is not recommended at this point, except if you
+want to contribute with it's development.
+
+But studying it's documentation, code, conventions is concepts is highly
+encouraged, as it may give you some ideas to manage your own systems.
