First Steps

In order to run ghc and cabal, you need to adjust your PATH variable.

To do so, you may want to run 'source /d/CLOUD/Programmier-Workshops/Kurse/Haskell/Programme/Haskell/ghcup/env' in your current terminal
session as well as your shell configuration (e.g. ~/.bashrc).
Start a simple repl via:
  ghci

Start a new haskell project in the current directory via:
  cabal init --interactive

Install other GHC versions and tools via:
  ghcup list
  ghcup install <tool> <version>

To install system libraries and update msys2/mingw64,
open the "Mingw haskell shell"
and the "Mingw package management docs"
desktop shortcuts.
