+These makefiles are recipes for several common tasks in different types of projects.
+To add them to your project, simply do:
+
+```
+git remote add makefiles ssh://git@lab.cluster.gsi.dit.upm.es:2200/docs/templates/makefiles.git
+git subtree add --prefix=.makefiles/ makefiles master
+touch Makefile
+echo "include .makefiles/base.mk" >> Makefile
+```
+
+Now you can take advantage of the recipes.
+For instance, to add useful targets for a python project, just add this to your Makefile:
+
+```
+include .makefiles/python.mk
+```
+
+You may need to set special variables like the name of your project or the python versions you're targetting.
+Take a look at each specific `.mk` file for more information, and the `Makefile` in the [senpy](https://lab.cluster.gsi.dit.upm.es/senpy/senpy) project for a real use case.
+
+If you update the makefiles from your repository, make sure to push the changes for review in upstream (this repository):
+
+```
+make makefiles-push
+```
+
+It will automatically commit all unstaged changes in the .makefiles folder.

+Advanced plugin definition
+--------------------------
+In addition to finding plugins defined in source code files, senpy can also load a special type of definition file (`.senpy` files).
+This used to be the only mechanism for loading in earlier versions of senpy.
+
+The definition file contains basic information 
+
+Lastly, it is also possible to add new plugins programmatically.
+
+.. contents:: :local:
+
+What is a plugin?
+=================
+
+A plugin is a program that, given a text, will add annotations to it.
+In practice, a plugin consists of at least two files:
+
+- Definition file: a `.senpy` file that describes the plugin (e.g. what input parameters it accepts, what emotion model it uses).
+- Python module: the actual code that will add annotations to each input.
+
+This separation allows us to deploy plugins that use the same code but employ different parameters.
+For instance, one could use the same classifier and processing in several plugins, but train with different datasets.
+This scenario is particularly useful for evaluation purposes.
+
+The only limitation is that the name of each plugin needs to be unique.
+
+Definition files
+================
+
+The definition file complements and overrides the attributes provided by the plugin.
+It can be written in YAML or JSON.
+The most important attributes are:
+
+* **name**: unique name that senpy will use internally to identify the plugin.
+* **module**: indicates the module that contains the plugin code, which will be automatically loaded by senpy.
+* **version**
+* extra_params: to add parameters to the senpy API when this plugin is requested. Those parameters may be required, and have aliased names. For instance:
+
+  .. code:: yaml
+
+            extra_params:
+                hello_param:
+                    aliases: # required
+                        - hello_param
+                        - hello
+                    required: true
+                    default: Hi you
+                    values:
+                        - Hi you
+                        - Hello y'all
+                        - Howdy
+
+A complete example:
+
+.. code:: yaml
+          
+          name: <Name of the plugin>
+          module: <Python file>
+          version: 0.1
+
+And the json equivalent:
+
+.. code:: json
+
+          {
+            "name": "<Name of the plugin>",
+            "module": "<Python file>",
+            "version": "0.1"
+          }
+
+
+Example plugin with a definition file
+=====================================
+
+In this section, we will implement a basic sentiment analysis plugin.
+To determine the polarity of each entry, the plugin will compare the length of the string to a threshold.
+This threshold will be included in the definition file.
+
+The definition file would look like this:
+
+.. code:: yaml
+
+          name: helloworld
+          module: helloworld
+          version: 0.0
+          threshold: 10
+          description: Hello World
+
+Now, in a file named ``helloworld.py``:
+
+.. code:: python
+
+          #!/bin/env python
+          #helloworld.py
+
+          from senpy import AnalysisPlugin
+          from senpy import Sentiment
+
+
+          class HelloWorld(AnalysisPlugin):
+
+              def analyse_entry(entry, params):
+                  '''Basically do nothing with each entry'''
+
+                  sentiment = Sentiment()
+                  if len(entry.text) < self.threshold:
+                      sentiment['marl:hasPolarity'] = 'marl:Positive'
+                  else:
+                      sentiment['marl:hasPolarity'] = 'marl:Negative'
+                  entry.sentiments.append(sentiment)
+                  yield entry

-Plugin Definition files
-=======================
-
-The definition file contains all the attributes of the plugin, and can be written in YAML or JSON.
-When the server is launched, it will recursively search for definition files in the plugin folder (the current folder, by default).
-The most important attributes are:
-
-* **name**: unique name that senpy will use internally to identify the plugin.
-* **module**: indicates the module that contains the plugin code, which will be automatically loaded by senpy.
-* **version**

-============
-
-The basic methods in a plugin are:
-
-* __init__
-* activate: used to load memory-hungry resources
-* deactivate: used to free up resources
-* analyse_entry: called in every user requests. It takes two parameters: ``Entry``, the entry object, and ``params``, the parameters supplied by the user. It should yield one or more ``Entry`` objects.
-
-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.

-Entries
-=======
+What is an entry?
+=================
 
 Entries are objects that can be annotated.
+In general, they will be a piece of text.
 By default, entries are `NIF contexts <http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core/nif-core.html>`_ represented in JSON-LD format.

-          version: 0.0
-          threshold: 10

+
+The lines highlighted contain some information about the plugin.
+In particular, the following information is mandatory:
+
+* A unique name for the class. In our example, Rand.
+* The subclass/type of plugin. This is typically either `SentimentPlugin` or `EmotionPlugin`. However, new types of plugin can be created for different annotations. The only requirement is that these new types inherit from `senpy.Analysis`
+* A description of the plugin. This can be done simply by adding a doc to the class.
+* A version, which should get updated.
+* An author name.
+
+
+Plugins Code
+============
+
+The basic methods in a plugin are:
+
+* analyse_entry: called in every user requests. It takes two parameters: ``Entry``, the entry object, and ``params``, the parameters supplied by the user. It should yield one or more ``Entry`` objects.
+* activate: used to load memory-hungry resources. For instance, to train a classifier.
+* deactivate: used to free up resources when the plugin is no longer needed.
+
+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.
+
+
+How does senpy find modules?
+============================
+
+Senpy looks for files of two types:
+
+* Python files of the form `senpy_<NAME>.py` or `<NAME>_plugin.py`. In these files, it will look for: 1) Instances that inherit from `senpy.Plugin`, or subclasses of `senpy.Plugin` that can be initialized without a configuration file. i.e. classes that contain all the required attributes for a plugin.
+* Plugin definition files (see :doc:`advanced-plugins`)
+
+Defining additional parameters
+==============================
+
+Your plugin may ask for additional parameters from the users of the service by using the attribute ``extra_params`` in your plugin definition.
+It takes a dictionary, where the keys are the name of the argument/parameter, and the value has the following fields:
+
+* aliases: the different names which can be used in the request to use the parameter.
+* required: if set to true, users need to provide this parameter unless a default is set.
+* options: the different acceptable values of the parameter (i.e. an enum). If set, the value provided must match one of the options.
+* default: the default value of the parameter, if none is provided in the request.

 Loading data and files
 ======================
 
 Most plugins will need access to files (dictionaries, lexicons, etc.).
+These files are usually heavy or under a license that does not allow redistribution.
+For this reason, senpy has a `data_folder` that is separated from the source files.
+The location of this folder is controlled programmatically or by setting the `SENPY_DATA` environment variable.
+
+Plugins have a convenience function `self.open` which will automatically prepend the data folder to relative paths:
+
+
+.. code:: python
+
+          import os
+
+
+          class PluginWithResources(AnalysisPlugin):
+              file_in_data = <FILE PATH>
+              file_in_sources = <FILE PATH>
+
+              def activate(self):
+                  with self.open(self.file_in_data) as f:
+                      self._classifier = train_from_file(f)
+                  file_in_source = os.path.join(self.get_folder(), self.file_in_sources)
+                  with self.open(file_in_source) as f:
+                      pass
+
+         
 It is good practice to specify the paths of these files in the plugin configuration, so the same code can be reused with different resources.

 What is Senpy?
 --------------
 
-Web services can get really complex: data validation, user interaction, formatting, logging., etc. 
-The figure below summarizes the typical features in an analysis service.
+Senpy is a framework for text analysis using Linked Data. There are three main applications of Senpy so far: sentiment and emotion analysis, user profiling and entity recoginition. Annotations and Services are compliant with NIF (NLP Interchange Format).
+
+Senpy aims at providing a framework where analysis modules can be integrated easily as plugins, and providing a core functionality for managing tasks such as data validation, user interaction, formatting, logging, translation to linked data, etc. 
+
+The figure below summarizes the typical features in a text analysis service.
 Senpy implements all the common blocks, so developers can focus on what really matters: great analysis algorithms that solve real problems.

+This is a collection of plugins that exemplify certain aspects of plugin development with senpy.
+
+The first series of plugins the `basic` ones.
+Their starting point is a classification function defined in `basic.py`.
+They all include testing and running them as a script will run all tests.
+In ascending order of customization, the plugins are:
+
+* Basic is the simplest plugin of all. It leverages the `SentimentBox` Plugin class to create a plugin out of a classification method, and `MappingMixin` to convert the labels from (`pos`, `neg`) to (`marl:Positive`, `marl:Negative`
+* Basic_box is just like the previous one, but replaces the mixin with a custom function.
+* Basic_configurable is a version of `basic` with a configurable map of emojis for each sentiment.
+* Basic_parameterized like `basic_info`, but users set the map in each query (via `extra_parameters`).
+* Basic_analyse\_entry uses the more general `analyse_entry` method and adds the annotations individually.
+
+
+In rest of the plugins show advanced topics:
+
+* mynoop: shows how to add a definition file with external requirements for a plugin. Doing this with a python-only module would require moving all imports of the requirements to their functions, which is considered bad practice.
+* Async: a barebones example of training a plugin and analyzing data in parallel.
+
+All of the plugins in this folder include a set of test cases and they are periodically tested with the latest version of senpy.
+
+Additioanlly, for an example of stand-alone plugin that can be tested and deployed with docker, take a look at: lab.cluster.gsi.dit.upm.es/senpy/plugin-example

+    Entities of the base model are a special kind of dictionary that emulates
+    a JSON-LD object. The structure of the dictionary is checked via JSON-schema.
+    For convenience, the values can also be accessed as attributes
+    (a la Javascript). e.g.:
+
+    >>> myobject.key == myobject['key']
+    True
+    >>> myobject.ns__name == myobject['ns:name']
+    True
+
+    Additionally, subclasses of this class can specify default values for their
+    instances. These defaults are inherited by subclasses. e.g.:
+
+    >>> class NewModel(BaseModel):
+    ...     mydefault = 5
+    >>> n1 = NewModel()
+    >>> n1['mydefault'] == 5
+    True
+    >>> n1.mydefault = 3
+    >>> n1['mydefault'] = 3
+    True
+    >>> n2 = NewModel()
+    >>> n2 == 5
+    True
+    >>> class SubModel(NewModel):
+            pass
+    >>> subn = SubModel()
+    >>> subn.mydefault == 5
+    True
+
+    Lastly, every subclass that also specifies a schema will get registered, so it
+    is possible to deserialize JSON and get the right type.
+    i.e. to recover an instance of the original class from a plain JSON.
