+#Flask and REST example
+
+A simple RESTful Flask CRUD, based on [snippet #38](http://flask.pocoo.org/snippets/38/).
+
+##Dependencies
+
+The only dependency is [Flask](http://flask.pocoo.org), that can be easily installed:
+
+    $ [sudo] pip install flask
+
+##Running it
+
+Just run on terminal:
+
+    $ python library.py
+
+And happy browsing! :)
