This book is divided into two tracks. The beginner's track (left) will introduce you to the very basics of the language and some of most frequently used libraries. This will enable you to build simple programs and prepare you for the advanced track. The advanced track (right) introduces functional programming concepts like monads, some new features of Haskell, such as Generalised Algebraic Data Types. At the very end of this book, we also have a set of chapters on the more day-to-day issues of working with Haskell, issues such as making use of the stardard library, building graphical interfaces or working with databases. You should be able to jump directly to this chapter from the basic track.
Please contribute! Everyone, regardless of Haskell competency, can help out. Spend five minutes improving a module and save someone else hours of time. Check out the notes for contributors.
