About the Book
Welcome to the totally awesome Happy Learn Haskell Tutorial series! It's an easy gradual method to learn functional programming together. It's totally free for you to read online (at http://www.happylearnhaskelltutorial.com), because everyone should be able to learn Haskell!
You will start from the absolute beginning, so you don't need to know any programming. On the other hand, if you've had some frustrations with it in the past, then this way of explaining might be just for you!
By buying one or more copies, and telling all your friends about it, you will support us in building more volumes (we have big plans, which we'd love to be able to do).
Why will this series be easier and better to learn with than others?
Tackling reading first, and slowly introducing writing when enough examples have been seen to increase confidence, because reading & writing are separate skillsMany small, fun examples for each thing to keep interest: fun examples helps with motivationGradual, partial introduction of topics, in context: graded, less to take in at onceNot so much theory introduced before the practical has been introduced (same as examples) which gives a context for the theoryPictures. Some of these are visual aides, which are useful as explanations: a picture tells 1000 wordsNo assumption of previous programming experience. Almost every other guide available assume some programmingSmaller sections because completing small things gives a real sense of achievement, which increases motivationTackling how to deconstruct problems using both top down and bottom up approaches: most guides don't tackle this in a simple or basics-first wayIt's free to read and online, so able to be discussed in public - some guides are, others aren'tNot so math focussed including "mathy jargon". We keep away from "frightening" terms like catamorphism, lambda calculus, monad, etc. and these are only introduced when appropriate amounts of knowledge are present through repeated exposure to examples, so that it's obvious what is meant

Packages
The Book
This package contains just the book in PDF format.
Includes:
Outdated (Feb 2016) ePub version
Many people request that we keep the outdated ePub version up, so this extra is to provide those people with that need. We're working on a new ePub version, but it won't be available for a little while as we have to build the code into our generator.
PDF
The Book + Code Samples
This package contains the book and Haskell stack projects that correspond to each chapter of the book so that it can be easily executed and experimented with.
Includes:
Vol 1 Code Samples
Volume 1 Code Samples as Stack Projects
Outdated (Feb 2016) ePub version
Many people request that we keep the outdated ePub version up, so this extra is to provide those people with that need. We're working on a new ePub version, but it won't be available for a little while as we have to build the code into our generator.

Great Reference
Your book serves as a great reference for all the definitions of Haskell terms and understandings. I am learning and I am passionate about learning with it. So, many thanks for your book, it's really helping me to understand Haskell better!
