+# scala-getting-started
+
+A barebones Scala app, which can easily be deployed to Heroku.  
+
+This application support the [Getting Started with Scala on Heroku](https://devcenter.heroku.com/articles/getting-started-with-scala) article - check it out.
+
+## Running Locally
+
+Make sure you have Scala and sbt installed.  Also, install the [Heroku Toolbelt](https://toolbelt.heroku.com/).
+
+```sh
+$ git clone https://github.com/heroku/scala-getting-started.git
+$ cd scala-getting-started
+$ sbt compile stage
+$ foreman start web
+```
+
+Your app should now be running on [localhost:5000](http://localhost:5000/).
+
+## Deploying to Heroku
+
+```sh
+$ heroku create
+$ git push heroku master
+$ heroku open
+```
+
+## Documentation
+
+For more information about using Scala on Heroku, see these Dev Center articles:
