See the Installation Prerequisites wiki page.
Ruby 2.1.0+ is required by Hydra-Head release 10+; RVM is strongly suggested.
gem install 'rails' --version '~>5.1.0'
Generate a new rails application:
rails new my_hydra_head cd my_hydra_head
First, add them to the Gemfile of your application. The new rails application you just generated will have generated a Gemfile; add blacklight and hydra-head as below:
source 'https://rubygems.org' gem 'rails' gem 'blacklight' gem 'hydra-head', '~> 10.0'
To install all of the dependencies, run:
Run the generators and migrations:
Run the blacklight generator
rails g blacklight:install --devise
Run the hydra-head generator
rails g hydra:head -f
Run the database migrations
Congratulations. You've set up the code for your Hydra Head.
