+# Ruby on Rails Tutorial sample application

+This is the sample application for
+[*Ruby on Rails Tutorial:
+Learn Web Development with Rails*](http://www.railstutorial.org/)
+by [Michael Hartl](http://www.michaelhartl.com/).
+
+## License
+
+All source code in the [Ruby on Rails Tutorial](http://railstutorial.org/)
+is available jointly under the MIT License and the Beerware License. See
+[LICENSE.md](LICENSE.md) for details.
+
+## Getting started
+
+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
+```
+
+For more information, see the
+[*Ruby on Rails Tutorial* book](http://www.railstutorial.org/book).
