-[Senpy](http://senpy.herokuapp.com) 
-=========================================
-Example endpoint that yields results compatible with the EUROSENTIMENT format and exposes the NIF API.
-It can be used as a template to adapt existing services to EUROSENTIMENT or to create new services.
-
-[DEMO on Heroku](http://eurosentiment-endpoint.herokuapp.com)
-
-This endpoint serves as bootcampt for any developer wishing to build applications that use the EUROSENTIMENT services.

+
+Senpy lets you create sentiment analysis web services easily, fast and using a well known API.
+As a bonus, senpy services use semantic vocabularies (e.g. `NIF <http://persistence.uni-leipzig.org/nlp2rdf/>`_, `Marl <http://www.gsi.dit.upm.es/ontologies/marl>`_, `Onyx <http://www.gsi.dit.upm.es/ontologies/onyx>`_) and formats (turtle, JSON-LD, xml-rdf).
+
+Have you ever wanted to turn your sentiment analysis algorithms into a service?
+With senpy, now you can.
+It provides all the tools so you just have to worry about improving your algorithms:
+
+`See it in action. <http://demos.gsi.dit.upm.es/senpy>`_
+
+Installation
+------------
+The stable version can be installed in three ways.
+
+Through PIP
+***********
+
+.. code:: bash
+
+   pip install --user senpy
+
+   
+Alternatively, you can use the development version:
+ 
+.. code:: bash
+
+   git clone git@github.com:gsi-upm/senpy
+   cd senpy
+   pip install --user .
+
+If you want to install senpy globally, use sudo instead of the ``--user`` flag.
+
+Docker Image
+************
+Build the image or use the pre-built one: ``docker run -ti -p 5000:5000 balkian/senpy --host 0.0.0.0 --default-plugins``.
+
+To add custom plugins, add a volume and tell senpy where to find the plugins: ``docker run -ti -p 5000:5000 -v <PATH OF PLUGINS>:/plugins balkian/senpy --host 0.0.0.0 --default-plugins -f /plugins``
+
+Usage
+-----
+
+However, the easiest and recommended way is to just use the command-line tool to load your plugins and launch the server.
+
+.. code:: bash
+
+   senpy
+
+or, alternatively:
+
+.. code:: bash
+
+    python -m senpy
+
+
+This will create a server with any modules found in the current path.
+For more options, see the `--help` page.
+
+Alternatively, you can use the modules included in senpy to build your own application.
+
+Deploying on Heroku
+-------------------
+Use a free heroku instance to share your service with the world.
+Just use the example Procfile in this repository, or build your own.
+
+
+`DEMO on heroku <http://senpy.herokuapp.com>`_
+
+
+For more information, check out the `documentation <http://senpy.readthedocs.org>`_.

+Installation
+------------
+The stable version can be installed in three ways.
+
+Through PIP
+***********
+
+.. code:: bash
+
+   pip install --user senpy
+
+   
+Alternatively, you can use the development version:
+ 
+.. code:: bash
+
+   git clone git@github.com:gsi-upm/senpy
+   cd senpy
+   pip install --user .
+
+If you want to install senpy globally, use sudo instead of the ``--user`` flag.
+
+Docker Image
+************
+Build the image or use the pre-built one: ``docker run -ti -p 5000:5000 balkian/senpy --host 0.0.0.0 --default-plugins``.
+
+To add custom plugins, add a volume and tell senpy where to find the plugins: ``docker run -ti -p 5000:5000 -v <PATH OF PLUGINS>:/plugins balkian/senpy --host 0.0.0.0 --default-plugins -f /plugins``

+Developing new plugins
+----------------------
+
+Plugins Interface
+=================
+
+The basic methods in a plugin are:
+
+* __init__
+* activate: used to load memory-hungry resources
+* deactivate: used to free up resources
+
+Plugins are loaded asynchronously, so don't worry if the activate method takes too long. The plugin will be marked as activated once it is finished executing the method.
+
+F.A.Q.
+======
+If I'm using a classifier, where should I train the classifier?
+???????????????????????????????????????????????????????????????
+
+Training a classifier can be time time consuming. To avoid running the training unnecessarily, you can use ShelfMixin to store the classifier. For instance:
+
+.. code:: python
+
+          from senpy.plugins import ShelfMixin, SenpyPlugin
+
+          class MyPlugin(ShelfMixin, SenpyPlugin):
+              def train(self):
+                  ''' Code to train the classifier
+                  '''
+                  # Here goes the code
+                  # ...
+                  return classifier
+
+              def activate(self):
+                  if 'classifier' not in self.sh:
+                      classifier = self.train()
+                      self.sh['classifier'] = classifier
+                  self.classifier = self.sh['classifier']
+              
+              def deactivate(self):
+                  self.close()
+
+You can speficy a 'shelf_file' in your .senpy file. By default the ShelfMixin creates a file based on the plugin name and stores it in that plugin's folder.
+
+Where can I find more code examples?
+????????????????????????????????????

+Usage
+-----
+
+The easiest and recommended way is to just use the command-line tool to load your plugins and launch the server.
+
+.. code:: bash
+
+   senpy
+
+Or, alternatively:
+
+.. code:: bash
+
+    python -m senpy
+
+
+This will create a server with any modules found in the current path.
+For more options, see the `--help` page.
+
+Alternatively, you can use the modules included in senpy to build your own application.
