This is the source code for a tutorial I wrote on my blog (in PT-BR).

Make sure you have Stack installed and run:

$ git clone https://github.com/alexandrelucchesi/haskell-scotty-tutorial.git
$ cd haskell-scotty-tutorial
$ stack build
$ stack exec -- mavins-lee

Optionally, instead of running build and exec, you can load the application into GHCi with stack ghci and call main from there. This is particurlaly useful during development.
