 # Decidim::BulletinBoard
 
-Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/decidim/bulletin_board`. To experiment with that code, run `bin/console` for an interactive prompt.
+The Bulletin Board is a service composed by an Encryption Engine and an Append-Only Log. External queries to the Encryption Engine are allowed through a GraphQL API (see https://github.com/decidim/decidim-bulletin-board).
 
-TODO: Delete this and the text above, and describe your gem
+This gem provides a collection of commands to interact with such API using Ruby, mainly for its use in a backend service.
 
 ## Installation
 
-Add this line to your application's Gemfile:
+Run this command to add the gem to your Gemfile:
 
-```ruby
-gem 'decidim-bulletin_board'
+```console
+bundle add decidim-bulletin_board
 ```
 
-And then execute:
-
-    $ bundle install
-
 Or install it yourself as:
 
-    $ gem install decidim-bulletin_board
+```console
+gem install decidim-bulletin_board
+```
 
 ## Usage
 
-TODO: Write usage instructions here
+Basic usage involves creating a client and using it to perform the desired operations:
+
+```ruby
+# Instantiate a client
+bulletin_board = Decidim::BulletinBoard::Client.new
+
+# Perform operations
+bulletin_board.cast_vote(election_id, voter_id, encrypted_data) do |message_id|
+  # Do something else with the message_id
+end
+```
+
+See a list of available operations here: https://github.com/decidim/decidim-bulletin-board/blob/develop/bulletin_board/ruby-client/lib/decidim/bulletin_board/client.rb

 - System dependencies:

-The Bulletin Board depends on the existence of a Decidim installation.
+The Bulletin Board is intended to use alongside a Decidim installation. Its main purpose is to provide a GraphQL interface to a secure, auditable and verifiable voting system. This is currently achieved by using the [ElectionGuard python implementation](https://github.com/microsoft/electionguard-python), developed by Microsoft. So this server acts as a [wrapper to the ElectionGuard python code](../../voting_schemes/electionguard/python-wrapper).

+This implementation is intended for testing purposes only. It allows to test the Bulletin Board without the need to use a fully configured Decidim installation.

+The Bulletin Board is a generic API for storing and retrieving ballots and tallies for elections. The final implementation of the protocol used for creating an election may vary. This gem provides the [Microsoft's ElectionGuard](https://github.com/microsoft/electionguard-python) Javascript implementation for production use in Decidim.
 
-TODO: Delete this and the text above, and describe your gem
+Note that the ElectionGuard implementation works by using two different wrappers around Electionguard:
+
+- A [Python Wrapper](../python-wrapper) for its use in the backend of the [GraphQL API server](../../../bulletin_board/server).
+- A [Javascript Wrapper](../js-adapter) that compiles the whole Electionguard python app into web-assembly and allows to use it in the frontend (this ensure that the voting process is not tampered by sending any data to the backend).
+
+This gem provides a very simple gem that wraps the Javascript implementation and allows to use it in the frontend of a Decidim application (Elections module).
