I learn a lot about Rails from Ruby on Rails Tutorial: Learn Web Development with Rails by Michael Hartl.
To get started with the app, clone the repo and then install the needed gems:
$ bundle install --without production
Next, migrate the database:
$ rails db:migrate
Finally, run the test suite to verify that everything is working correctly:
$ rails test
If the test suite passes, you'll be ready to run the app in a local server:
$ rails server
