+Moulinette
+==========

- 
-Moulinette is a small Python framework meant to easily create programs with unified CLI and API.
+The *moulinette* is a Python package that allows to quickly and easily
+prototype interfaces for your application.

-In particular, it is used as a base framework for the YunoHost project.

 Overview
 --------

-Moulinette allows to create a YAML "actionmaps" that describes what commands are available. Moulinette will automatically make these commands available through the CLI and Web API, and will be mapped to a python function. Moulinette also provide some general helpers, for example for logging, i18n, authentication, or common file system operations.
+Initially, the moulinette was an application made for the
+[YunoHost](https://yunohost.org/) project in order to regroup all its
+related operations into a single program called *moulinette*. Those
+operations were available from a command-line interface and a Web server
+providing an API. Moreover, the usage of these operations (e.g.
+required/optional arguments) was defined into a simple yaml file -
+called *actionsmap*. This file was parsed in order to construct an
+*ArgumentParser* object and to parse the command arguments to process
+the proper operation.

-<div align="center"><img src="doc/actionsmap.png" width="700" /></div>
+During a long refactoring with the goal of unify both interfaces, the
+idea to separate the core of the YunoHost operations has emerged.
+The core kept the same name *moulinette* and try to follow the same
+initial principle. An [Actions Map](#actions-map) - which defines
+available operations and their usage - is parsed and it's used to
+process an operation from several unified [Interfaces](#interfaces). It
+also supports a configuration mechanism - which allows to restrict an
+operation on an interface for example (see
+[Authenticators](#authenticators)).
