Haskell Installation

• install Visual Studio Code
• install GHCup
• select all "default" options
• answer "Do you want to install haskell-language-server (HLS)?" with "Yes"

Then run these commands:

ghcup install ghc 9.10.3
ghcup set ghc 9.10.3

To test the installation:

• start VSCode via code . in this folder
• install the haskell.haskell extension
• in the file haskell-code/Intro.hs, delete a character in where
• after some time (it should show processing in the bottom bar), you should see red squiggles (not just red letters)
