+## How cdist works
+
+### Exploring your system
+
+cdist analyses the system to apply the configuration on and
+selects the right backends. You can use ***cdist-explore*** to
+the results of the explore functions.
+
+### Applying the configuration
+
+cdist looks for the configuration to apply on the local host
+and applies it using ***cdist-apply***.
+
+### Managing many hosts
+
+Whereas ***cdist-apply*** manages one host, ***cdist-deploy***
+applies the configuration on enabled hosts.
