+node-notes is a node.js version of Rails' "rake notes" functionality. It allows you
+to put comments in your code and then have them annotated across your whole project. Uses local ``.gitignore`` to ignore files or default ignore list.
 
 ### Installation:
 
-
     npm install notes -g
 
 ### Usage:
 
     $ notes              # will search for notes in cwd
+    $ notes .            # will search for notes in cwd considers .gitignore to ignore files
     $ notes lib/ test/   # will search only in lib and test
