 After installing with `cabal install json-autotype`, you might generate stub code for the parser:
 
 ```
-    json-autotype input.json -o MyFormat.hs
+    json-autotype input1.json ... inputN.json -o MyFormat.hs
 ```
 
 Then you might test the parser by running it on an input file:

-If everything is correct, then feel free to inspect the data structure generated automatically for you!
+At this point you may see data structure generated automatically for you.
+The more input files you give to the inference engine `json-autotype`,
+the more precise type description will be.
+
+Algorithm will also suggest which types look similar, based on a set of attribute names,
+and unify them unless specifically instructed otherwise.

 The goal of this program is to make it easy for users of big JSON APIs to generate entries from
 example data.
