Yesod tutorials and examples can be found on the Yesod book, which is freely available online.

However, many of the examples given are self-contained (which means that handler functions, data models and templates are defined in a single module, where a Warp web server is started as well). There is a chapter that describes the scaffolded template, i.e. what you get after you start with Yesod, but it is rather a description of its advantages and structure, not so much a detailed how-to.

The purpose of this post is to explain to a new Yesod developer “What do I do after … ?” :

$ yesod init
