 ## Creating/manipulating resources
 
+Working with file based definitions you can issue the lifecycle commands using the same input file:
+
     kubectl create -f some.json
-    kubectl delete -f some.json                   # Useful to delete the same resources with the same YAML!
-    
-    kubectl edit <type> <resource>                # Edit live, will automatically restart stuff
+    kubectl apply  -f some.json
+    kubectl diff   -f some.json
+    kubectl delete -f some.json
 
-    kubectl get rc <node> -o yaml >some.yaml
-    kubectl update -f some.yaml
+Note that you can alway use `--dry-run` to review the effective changes
+
+For existing resources you can use specific commands
     
+    kubectl edit <type> <resource>                # Edit live, will automatically restart stuff
+    kubectl delete <type> <resource>
