-Introduction
-============
-
-What is  `Google AppEngine` ?
-------------------------------
-
-`Google AppEngine`_ is provided with a partial port of the `Django`
-framework, but Google stated at Google IO 2008 that it would not
-support a specific Python web framework and that all
-community-supported frameworks would be more than welcome [1]_. 
-
-Therefore `Logilab`_ ported `CubicWeb` to run on top of `Google AppEngine`'s
-datastore.

-Essentials
-----------
-
-To build a web application for `Google App Engine`'s datastore, you
-need to have a good understanding of the main concepts of our 
-`CubicWeb` framework.
-
-The main concepts are:
-
-  - *schema*
-
-  - *query language*
-
-  - *result set*
-
-  - *views*
-
-  - *generated user interface*
-
-  - *cube*
-
-You can find detailled explanation of those concepts in :ref:`TermsVocabulary`.
