Compilation instructions (for Mac OS)

Install chruby and ruby-install from Homebrew for proper management of Ruby versions:

brew install chruby ruby-install 

Then use ruby-install to fetch and install the latest stable Ruby:

ruby-install ruby-3

Then use chruby to select Ruby 3 as the current version and check that it works properly:

chruby ruby-3
ruby --version

Then simply run bundle install and bundle exec jekyll serve to grab the dependencies and build & serve the website.
