title: How to generate active_admin:install on active admin rails 5 primary support?
body: <p>Activeadmin <a href="https://github.com/activeadmin/activeadmin" rel="nofollow noreferrer">readme</a> suggests to use following to use for primary support on rails 5.</p>
  
  <pre><code>gem 'inherited_resources', github: 'activeadmin/inherited_resources
  </code></pre>
  
  <p>Even after <code>$ bundle install</code> it says there is no <code>active_admin:install</code> generator available.</p>
  
  <pre><code>$ rails generate active_admin:install
  Running via Spring preloader in process 6209
  Could not find generator 'active_admin:install'. Maybe you meant 'responders:install', 'active_record:model' or 'active_record:migration'
  Run `rails generate --help` for more options.
