Tutorial "Control Your Effects in Haskell"

To prepare for the tutorial, you have two choices:

If you're proficient with Haskell and have Haskell and cabal installed

cabal install --dependencies-only

You probably will need ghc 8.8 - Polysemy doesn't work with 8.10.

install Docker
on Docker for Mac, give it >=6GB via Preferences -> Resources -> Memory
install Visual Studio Code
install the "ghcide" extension: click on the "Extensions" icon on the left, search for "ghcide", select "ghcide", click on install
install the "Remote - Containers" extension: click on the "Extensions" icon on the left, search for "Containers", select "Remote - Containers", click on install
click on the files icon in the upper-left corner
click on the "View" item, select "Command Palette", type "containers", select "Remote - Containers: Open Folder in Container"
select the prep or the live folder
it should say that it's building a docker image; this can take a while (possibly an hour or more, 20mins on my machine)
