 ### Deployment Policy 
 
-- Deployment Policy (sometimes called Deployment Policy) is what ties together Edge Nodes, Published Services, and the Policies defined for each of those, making it roughly analogous to the Deployment Patterns you have previously worked with.

 - Deployment Policy, like the other two Policy types, contains a set of `properties` and a set of `constraints`, but it contains other things as well. For example, it explicitly identifies the Service it will cause to be deployed onto Edge Nodes if negotiation is successful, in addition to configuration variable values, performing the equivalent function to the `-f horizon/userinput.json` clause of a Deployment Pattern `hzn register ...` command. The Deployment Policy approach for configuration values is more powerful because this operation can be performed centrally (no need to connect directly to the Edge Node).
