https://en.wikibooks.org/wiki/Haskell I really liked the wikibook when I was learning Haskell. It's not as in depth, and does not cover all of the topics - but it's a great starting point.
http://dev.stephendiehl.com/hask/ What I wish I knew when learning Haskell - INCREDIBLY resourceful community edited document into a whole range of Haskell related topics. debugging, editors, frameworks etc. This thing is huge!
http://fpchat.com - a slack community. There is a dedicated #haskell-beginners channel. A great community - which was a HUGE help to me when I first started learning.
ghcid, which automatically reloads (compiles) your code within GHCI (the Haskell interpreter implementation) and shows relevant errors. Did I also mention it's incredibly fast, perhaps even instantaneous? https://github.com/ndmitchell/ghcid
