 ## Setup
 First of all, you need configure the dspace, elasticsearch and redis servers. An user for postgres database will be needed to.
 After this setup, open the config files and update some vars:
+
     * config/database.yml: change your postgres credentials for development and test environment.
     * config/dspace.yml: change your dspace host and credentials for development and test environment.
     * config/sidekiq.yml: change your redis hosts and ports.
