The easiest way to get started is use Nix to set up the required toolchains. Suppose you have Nix installed, then just

$ nix develop

After that, you will be in a nix shell with all the needed toolchains available on the command line. We also add Just command runner for convenience. For example, to build or publish the package:

$ just build

$ just publish

Use just --list or see the Justfile for all the available recipes.
