# Trestle Authentication (trestle-auth) > Authentication plugin for the Trestle admin framework ## Getting Started These instructions assume you have a working Trestle application. To integrate trestle-auth, first add it to your application's Gemfile: ```ruby gem 'trestle-auth' ``` Run `bundle install`, and then run the install generator to set up configuration options, user model and user admin resource. $ rails generate trestle:auth:install $ rake db:migrate Then create an initial admin user from the rails console: $ rails console > Administrator.create(email: "admin@example.com", password: "password", first_name: "Admin", last_name: "User") After restarting your Rails server, any attempt to access a page within your admin will redirect you to the login page. ## License The gem is available as open source under the terms of the [LGPLv3 License](https://opensource.org/licenses/LGPL-3.0).
