+Deployment on a custom machine
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Prerequisites
+=============
+
+You will need the following:
+
+* A clone of the git repository at ``https://git.laquadrature.net/memopol/memopol.git``
+* A dedicated python virtualenv
+* a PostgreSQL>=9.2 database (not necessarily on the same machine)
+* a WSGI-capable web server
+
+Setup environment
+=================
+
+Set the following environment variables::
+
+    DJANGO_SETTINGS_MODULE=memopol.settings
+
+Customize settings
+==================
+
+Create a copy of the example local settings file::
+
+    $ cp src/memopol/local_settings.py.example src/memopol/local_settings.py
+
+Edit ``src/memopol/local_settings.py`` to set directories, database settings and
+allowed hosts.  Setup your WSGI server to serve:
+
+* Static files from the directory specified in the ``PUBLIC_DIR`` setting to the
+  ``/static`` URL
+* The ``src/memopol/wsgi.py`` WSGI application
+
+Initial memopol setup
+=====================
+
+From the repository root, install python dependencies (you may want to do that
+in a virtualenv)::
+
+    $ pip install -U pip setuptools
+    $ pip install -Ue .
+
+Install client libraries::
+
+    $ src/memopol/bin/install_client_deps.sh
+
+Setup the database schema::
+
+    $ memopol migrate --noinput
+
+Collect static files::
+
+    $ memopol collectstatic --noinput
+
+Memopol should be ready to go.
+
+Updating
+========
+
+To update simply pull the repository and run setup commands again::
+
+    $ git pull
+    $ pip install -Ue .
+    $ src/memopol/bin/install_client_deps.sh
+    $ memopol migrate --noinput
+    $ memopol collectstatic --noinput
+
+Data provisionning
+==================
+
+Set up two cron jobs:
+
+* One to update data from parliaments, that runs ``bin/update_all``.  This
+  script takes quite some time to run, so you should schedule it once every
+  night for example
+* One to refresh scores,  that runs ``memopol refresh_scores``.  This one
+  runs quite quickly (a few seconds), you may want to run it after the update
+  job has completed (but you can run it more often).
+
+Ensure that cron jobs get the same environment as the application.
+
+
+Continue to :doc:`administration`.

-Deployment on OpenShift
-~~~~~~~~~~~~~~~~~~~~~~~
-
-OpenShift is an Open-Source Platform-as-a-Service software by Red Hat. It is
-also available in its hosted version known as "OpenShift Online" and the first
-three websites ("gears") are free.
-
-Clone the repository
-====================
-
-You should fork the project on github and use the fork's clone url. For the
-sake of the demo, we'll use the main repository URL::
-
-    $ git clone https://github.com/political-memory/political_memory.git
-    Cloning into 'political_memory'...
-    remote: Counting objects: 2516, done.
-    remote: Compressing objects: 100% (109/109), done.
-    remote: Total 2516 (delta 44), reused 0 (delta 0), pack-reused 2402
-    Receiving objects: 100% (2516/2516), 4.40 MiB | 79.00 KiB/s, done.
-    Resolving deltas: 100% (1103/1103), done.
-    Checking connectivity... done.
-
-    $ cd political_memory/
-
-Create your own branch, ie::
-
-    $ git checkout -b yourbranch origin/pr
-    Branch yourbranch set up to track remote branch pr from origin.
-    Switched to a new branch 'yourbranch'
-
-Create an app on OpenShift
-==========================
-
-To deploy the website, use a command like::
-
-    $ rhc app-create \
-        python-2.7 \
-        cron-1.4 \
-        postgresql-9.2 \
-        -a yourappname \
-        -e OPENSHIFT_PYTHON_WSGI_APPLICATION=memopol/wsgi.py \
-        --from-code https://github.com/political-memory/political_memory.git \
-        --no-git
-
-This should create an app on openshift. Other commands would deploy it at once
-but in this tutorial we're going to see how to manage it partly manually for
-development.
-
-Add the git remote created by OpenShift
-=======================================
-
-Add the git remote openshift created for you, you can see it with
-``rhc app-show``, ie.::
-
-    $ rhc app-show -a yourappname
-    [snip]
-    Git URL:         ssh://569f5cf500045f6a1839a0a4@yourappname-yourdomain.rhcloud.com/~/git/yourappname.git/
-    Initial Git URL: https://github.com/political-memory/political_memory.git
-    SSH:             569f5cf500045f6a1839a0a4@yourappname-yourdomain.rhcloud.com
-    [snip]
-
-    $ git remote add oo_yourappname ssh://569f5cf500045f6a1839a0a4@yourappname-yourdomain.rhcloud.com/~/git/yourappname.git/
-
-Activate OpenShift's git post-recieve hook
-==========================================
-
-Activate OpenShift's post-receive hook on your branch::
-
-    $ rhc app-configure -a yourappname --deployment-branch yourbranch
-
-Deploy your branch
-==================
-
-OpenShift will deploy when it receives commits on the deployment branch, to
-deploy just do::
-
-    $ git push oo_yourappname yourbranch
-
-If something goes wrong and you want to retry, use the ``rhc app-deploy``
-command, ie::
-
-    $ rhc app-deploy yourbranch -a yourappname
-
-Data provisionning
-==================
-
-To fill up the representatives database table, either wait for the cron script
-to be executed, either do it manually::
-
-    $ rhc ssh -a yourappname 'cd app-root/repo/ && bin/update_all'
-
-OpenShift is fun, login with ssh and look around if you're curious, you'll be
-able to recreate your app without much effort if you break it anyway.

+development on Linux. It requires git, a fairly recent version of python2,
+virtualenv and PostgreSQL.
+
+Setup the database
+==================
+
+Memopol requires PostgreSQL 9.1 or higher.  It used to run with SQLite, too, but
+that is no longer the case. It is better to install and configure you're local
+PostgreSQL server before starting to install Memopol.
+
+On Debian
+---------
+
+To setup you're PostgreSQL database on a debian stable distribution, you can use
+the package manager apt::
+
+  $ apt install postgresql postgresql-server-dev-9.X
+
+Then you need to create the 'memopol'  user and the 'memopol' database::
+
+  # To have a root access on Postgres, you need to connect as user 'postgres'
+  $ su - postgres
+  $ psql -c "create user memopol with password 'memopol';"
+  $ psql -c "alter role memopol with createdb;"
+  $ psql -c "create database memopol with owner memopol;"
+  $ exit
+
+You're database is now setup for Memopol. You can now launch the 'quickstart.sh'
+script to automatically install all the components or do it manually.
+
+In General
+----------
+
+Make sure the corresponding user and database exist on your system; the user
+will need the 'createdb' permission in order to be able to run tests.  To create
+them, you may use the following commands::
+
+    $ psql -c "create user memopol with password 'memopol';" -U postgres
+    $ psql -c "alter role memopol with createdb;" -U postgres
+    $ psql -c "create database memopol with owner memopol;" -U postgres
+
+
+Automatic Install
+=================
+
+There is a quickstart script used and tested manually by some of the
+developers. Feel free to try it, but don't worry if it doesn't work for you
+then you can do each install step manually, which is recommended because well
+that's how you will learn most.
+
+Here's how to try it::
+
+    $ git clone gitlab@git.laquadrature.net:memopol/memopol.git
+    $ cd memopol
+    $ source bin/quickstart.sh
+
+At this point, you should now run the development server and access to Memopol::
+
+  $ memopol runserver
+
+If you want more control or if it doesn't work for you, then follow the steps
+below or have a look at what the quickstart script does.
+
+Development helper
+===================
+
+You can run the script 'bin/dev.sh' to automaticaly setup some aliases. It works
+only with Bash and Zsh.
+
+The script build a custom file named '.memopol.alias' at the root of the project
+containing all the aliases for memopol. All the path to the project are build
+automatically. A single line is added to your '$HOME/.bashrc' or '$HOME/.zshrc'
+to source the aliases.
+
+After execute 'bin/dev.sh' you should close the current terminal and open
+another one to have access to the aliases.
+
+There is a quick list of available aliases::
+
+  memopol-code : Go into the repository and activate virtualenv and
+  set Django in debug mode
+  memopol-launch : Run the development server echo
+  memopol-update-all : Get all the production data
+  memopol-refresh-scores : Refresh all scores
+
+.. warning:: If you are using multiple setup of Memopol, it is not recommended to
+  use this script.
+
+If you need to change the location of the project, you should remove this line
+from your .bashrc or .zshrc::
+
+  source $PATH_TO_THE_PROJECT/.memopol.alias

+Memopol Scores
+~~~~~~~~~~~~~~
+
+Score computation
+=================
+
+In Memopol, each representative has a score that shows how their votes match
+the recommendations made by administrators on the instance.  The total score
+of a representative is the sum of their score on each dossier, which in turn is
+the sum of their score on each proposal with a recommendation on the dossier.
+
+Each recommendation made by administrators has a weight: a number that tells how
+important a specific proposal is.  When the representative vote on a proposal
+matches the recommendation, their score on the proposal is set to +weight.
+Otherwise, it is set to -weight.
+
+Score decay parameters
+======================
+
+Memopol allows to set decay parameters so that older votes have a lower
+importance in the total representative score.  By default, those parameters are
+set to values that disable the score decay, so that each vote contributes
+identically to the total score no matter how old it is.
+
+The formula used to compute score is the following:
+
+.. image:: img/score_formula.png
+
+Where:
+
+* ``baseScore`` is the base score for the vote computed as explained above;
+* ``voteAge`` is the age of the vote in days;
+* ``decayNum`` and ``decayDenom`` define the decay rate;
+* ``exponent`` define the steepness of the decay.
+
+The corresponding parameters can be set from the Memopol administration
+interface (Memopol Settings > Settings); settings keys are ``SCORE_DECAY_NUM``,
+``SCORE_DECAY_DENOM``, ``SCORE_EXPONENT``. Additionnaly, the ``SCORE_DECIMALS``
+parameter sets how many decimal places are visible when scores are displayed.
+
+The default values for those settings disable score decay by setting
+``SCORE_DECAY_NUM`` to 0, ``SCORE_DECAY_DENOM`` and ``SCORE_EXPONENT`` to 1.
+
+If you want to use score decay, start by setting ``SCORE_DECAY_NUM`` to 1, and
+``SCORE_DECAY_DENOM`` to the number of days you want votes to matter.  The graph
+below shows how a score of 1.0 will decay with a 1-year decay (the X axis is in
+days).
+
+.. image:: img/score_1year.png
+
+Increasing ``SCORE_DECAY_DENOM`` will make votes matter longer.  Here is the
+same example but with a 10-year decay.
+
+.. image:: img/score_10years.png
+
+Increasing ``SCORE_EXPONENT`` instead will make the decay cutoff steeper.  Here
+is an example with a 1-year decay and the exponent set to 6.
+
+.. image:: img/score_exp6.png
+
+Increasing it dramatically will create a brutal cutoff; here is the same example
+with the exponent set to 1000:
