+# Parentage
+
+Hubblestack started life as a Salt execution module meant to be
+run in a Salt environment. It later evolved into a stand alone
+daemon by borrowing heavily from the Salt daemon code.
+
+The next stage in this evolution is to remove the salt-ssh
+dependency from Hubblestack. This dependency is/was essentially
+all of Salt.
+
+The removal of the Salt dependency is not meant to hide or
+occlude this relationship. The point is to remove the parts of
+Salt that Hubblestack nolonger needs (the minion/master
+relationship, any sort of message bus, various types of template
+systems, and a few other things) and to avoid having to worry
+about surprise upstream changes that break Hubblestack.
+
+# Licensing
+
+The Apache license requires, among other things, that we do not
+remove any copyright or license information from any files copied
+into Hubblestack from Salt. It may be the case that some parts of
+Hubblestack are direct or even indirect copies of concepts from
+Salt that may not have carried a specific license at the time.
+
+Hubblestack has the same LICENSE file as Salt. Should there every
+be any doubt about the origin of a section of code in the future,
+please assume that it did come from Salt; and should therefore
+carry whatever LICENSE restrictions it did in Salt.
