Install Sinatra

The Sinatra gem has been installed, and a very basic Sinatra app has been created. It only service the root url, and returns a static string.
Install ActiveRecord

We want to use ActiveRecord as the ORM, combined with Postgres as the database. This decision is partly driven by our plan to deploy to Heroku later on.
Install Sinatra::Contrib

This gem contains a bunch of helpful modules for Sinatra, one of which is the support for JSON.
Install and require rake

sinatra-activerecord provides some useful task that require rake.
Install will_paginate

This gem provides pagination for models, and thus allows us to limit the size of responses very efficiently.
Install unicorn

Unicorn is an application server that can handle multiple requests at once using multithreading. This provides a significant performance boost compared to WEBrick.

Install Faraday

We use Faraday to query the authentication service to validate a user's token.
Install dotenv

Dotenv is used to configure the environment.
Provide protection for endpoints

A custom Sinatra extension has been implemented that handles the verification of a user token. Endpoints can be protected using the method "protected!", which returns 401 if the user cannot be authenticated.
