Haskell on Heroku is a Heroku buildpack for deploying Haskell apps.
Follow the Haskell on Heroku tutorial to get started.
Haskell on Heroku, like other Heroku buildpacks, can be used when creating a new Heroku app:
$ heroku create -b https://github.com/mietek/haskell-on-heroku
Push the code to Heroku in order to deploy your app:
$ git push heroku master
Start with the Haskell on Heroku tutorial to learn how to develop a simple Haskell web app and deploy it to Heroku.
Read the Halcyon tutorial to learn more about developing Haskell apps using Halcyon.
See the Haskell on Heroku reference for a list of buildpack-specific options.
Look for additional options in the Halcyon reference.
